Explanation

Costs of operating an asset can widely vary. The following table is an example from Guide to Total Cost of Ownership, New Zealand Government:

Explanation

The design of a building should consider the advantages of natural light as this can reduce the cost of artificial lighting and improve the environmental performance of the building. Daylight entering the building can also help reduce heating costs. Unfortunately some stocks react badly to direct sunlight, and some stock reacts badly to extreme of temperature or may require a specific temperature for storage. Some stock may require a warmer temperature than the ambient temperature and other stocks may require cooler temperature. For example, fabric and garment are sensitive to direct sunlight as ultraviolet light catalyses a reaction between the water present in all fabrics and atmospheric oxygen to create hydrogen peroxide. This is a bleaching agent and breaks down the chemical bonds that give dyes their colour.

Explanation

Void filling is the general term giving to the challenge of filling the space left in a box after the products have been packed. This means that if there is no void filling material, the product inside can move around and could be damaged. Materials to fill voids to secure contents

• Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene.[5] Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point.[6] Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year.[7] Polystyrene can be naturally transparent, but can be coloured with colourants. Uses include protective packaging (such as packing peanuts and CD and DVD cases), containers, lids, bottles, trays, tum-blers, disposable cutlery[6] and in the making of models. Polystyrene is generally considered to be non-biodegradable. However, certain organisms are able to degrade it, albeit very slowly.

• Chips made of bio-degradable materials

• Absorbent and fire-resistant material

• Shredded paper, cardboard or wood-Based material

• Paper or cardboard rolls

• Bubble wrap

• Air-filled cushions

• Self expanding foam

Straps are used to group items into unit load. Polypropylene or polyester are the materials most often used. The wider the strap, the stronger it will be. Using more than one strap and straps for length and width will create a strong place for stock.

Explanation

Scheduled maintenance is any repair and upkeep work performed within a set timeframe. It details when given maintenance tasks are performed and by whom. Scheduled maintenance may occur at repeating intervals or in response to a work request.

"Overhauling of machine" means that the machine is regularly checked and corrupted parts are replaced if needed.

"Cleaning of tank" and "Oil changes" also occur at time intervals as scheduled

So the correct answer is "Repair signage damage from a recent storm"

Explanation

The normal breakdown in a manufacturing organisation would be raw materials, components, work in progress and finished goods.

Following are the different types of inventory:

Raw materials are the basic materials that a manufacturing company buys from its suppliers, and that is used by the former to convert them into the final products by applying a set of manufacturing processes. For example, aluminum scrap is the raw material for a company that produces aluminum ingots. Flour is the raw material for a company that produces bread or pizza. Similarly, metal parts and ingots are the raw materials bought by a company that manufactures cars, and crude oil is the raw material for an oil refinery.

Work in progress inventory can also be called semi-finished goods. They are the raw materials that have been taken out of the raw materials store and are now undergoing the process of their conversion into the final products. These are the partly processed raw materials lying on the production floor. And they have also not reached the stage where they have been converted into the final product.

Finished goods are indeed the final products obtained after the application of the manufacturing processes on the raw materials and the semi-finished goods discussed above in the article. They are saleable, and their sale contributes fully to the revenue from the core operations of the company.

Explanation

VACUUM LIFTER uses the vacuum pad which attaches itself to a product. The suction force al-lows the product to be lifted (and rotated and placed). Vacuum lifters are used for moving and positioning glass sheets, but are also seen lifting boxes, plastic sacks, sheets of building materials and pipework. Some models feature hydraulic arms which allow easy movement of the lifted load. The lifting system will have a number of sucker pads and vacuum capability which determines the maximum weights and largest items that can be lifted.

DOLLY consists of stack and sets of wheels (either casters or rollers) under the stack that allow the dolly and the heavy object on top of it to move easily and smoothly. For moving in a straight line, rollers is ideal. If you want to move manoeuvrability, dolly with sets of casters will let you swivel and turn.

SACK TRUCK (hand truck) is an L-shaped box-moving handcart. It comprises a small base plat-form with two wheels at the base and a larger vertical structure. A small ledge to set objects on flat against the floor when the sack truck is upright. When moving, the truck and object are then tilted backward based on the vertical structure until the weight is balanced over the large wheels, making otherwise bulky and heavy objects easier to move.

PALLET STACKER is designed to lift and stack pallets. This one is fully mobile so can move easily around the warehouse. An operator would typically sit or stand while driving like a counter-balanced, reach or straddle lift truck.

Explanation

Price setting mechanisms fall into two main categories: fixed and variable. A fixed price mecha-nism is a straightforward concept which typically results in a relatively stable budget that can be forecast. Variable mechanisms have an element of variable pricing per unit bought.

Setting a fixed price mechanism is in theory a relatively simple and straightforward concept, where the collector and the buyer agree on a fixed price for a specific material or mix of materials, for a certain length of time.

All other pricing mechanisms that are not fixed have an element of variable pricing per unit bought.

The most common variable pricing mechanisms can be divided into two groups:

1. Where the benefit accruing to the buyer from acquiring the material is used to calculate what the payment to the seller should be; or Approaches to Materials Sales: A guide for local authorities

2. Where the price paid is indexed to a published source of market price information. The above scenario demonstrates variable pricing mechanism using published sources on inflation rate and exchange rate. CIPS also refers this mechanism as adjustable prices.

Explanation

Vendor Managed Inventory (VMI) is a business model where the buyer of a product provides in-formation to a vendor of that product and the vendor takes full responsibility for maintaining an agreed inventory of the material, usually at the buyer's consumption location.

Floor-Ready Merchandise can be defined as the merchandise that is pre-tagged, pre ticketed and pre-occupied with all the necessary details and information such as marked to their specifications for style, size, type, color and price, this information is required in the retail store and is done before it reaches the retail store.

Economic order quantity (EOQ) is the ideal order quantity a company should purchase to minimize inventory costs such as holding costs, shortage costs, and order costs. This production-scheduling model was developed in 1913 by Ford W. Harris and has been refined over time. The formula assumes that demand, ordering, and holding costs all remain constant.

The full definition of reverse logistics, as according to The Council of Logistics Management, is the process of implementing, controlling, and planning the cost-effective flow of finished goods, raw materials, and in-process inventory. The flow is from the point of consumption (i.e. the customer) to the point of origin (i.e. the manufacturer), to properly dispose of these or to recapture value.

In the scenario, XYZ solves the current situation by letting the supplier to management the inventory and sharing stock level information with the supplier. Vendor managed inventory is the most suitable answer.

Explanation

Maintenance can represent a significant portion of the cost in asset intensive organisations (such as Sidel - a food processor), as breakdowns have an impact on the capacity, quality and cost of operation. However, the formulation of a maintenance strategy depends on a number of factors, including the cost of down time, reliability characteristics and redundancy of assets. Consequently, the balance between preventive maintenance (PM) and corrective maintenance (CM) for minimising costs varies between organisations and assets. Nevertheless, there are some rules of thumb on the balance between PM and CM, such as the 80/20 rule.

Preventive maintenance is a type of proactive maintenance, while corrective maintenance is an example of reactive maintenance. Therefore, the answer should be "Balance between proactive maintenance and reactive maintenance".

Explanation

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate. RFID Antennas are necessary elements in an RFID system be-cause they convert the RFID reader’s signal into RF waves that can be picked up by RFID tags. Without some type of RFID antenna, whether integrated or stand-alone, the RFID reader cannot properly send and receive signals to RFID tags.

Explanation

Direct and indirect costs of holding inventory include the following:

1. Acquisition costs

2. Holding costs (carrying costs) are the costs associated with the storage and handling of physical stock. There are two different types of holding costs:

a. Costs related to the value of the goods: financial costs (i.e. the interest on the working capital tied up in inventory, which may be the bank borrowing rate or the company's target for return on capital); cost of insurance; losses due to product deterioration; losses due to obsolescence and redundancy of inventory; losses due to theft, accidental damage etc.

b. Costs related to the physical characteristics of the inventory include the following: storage space; power, heat and lighting of the store; movement equipment; labour costs; administration costs.

3. Costs of stockouts

Explanation

The bullwhip effect (or Forrester effect) is a distribution channel phenomenon in which forecasts yield supply chain inefficiencies. It refers to increasing swings in inventory in response to shifts in customer demand as one moves further up the supply chain.

Seasonal demand: consumer interest in purchasing particular products only during a specific peri-od within the calendar year.

OPITZ is a coding system used to form Groups in Group Technology philosophy of Manufactur-ing.

The Pareto Curve is the shape created when the bars of a Pareto Chart are progressively summed and the points joined together. The final curve ends at 100% of items in the chart, which means that you can then draw a line across at 80% and 'bounce' it down to find the bar which, when combined with all bars to its left, will give 80% of all items.

Explanation

Where stock turn (inventory turnover) is low and there are potential risks of redundancy or obsolescence, the buying organisation may adopt vendor owned stock. In this system, a supplier (vendor) maintains a stock of items ready to be used at the point of customer consumption. The supplier owns the stock until it is used by the purchaser; only then is the purchaser invoiced for it.

Just in case and larger safety stock would significantly increase the stock level, which may cause redundancy or obsolescence.

Forrester effect (or Bullwhip effect) is a distribution channel phenomenon in which forecasts yield supply chain inefficiencies. It refers to increasing swings in inventory in response to shifts in customer demand as one moves further up the supply chain.

Explanation

The most basic alarm consists of one or more sensors to detect intruders, and an alerting device to indicate the intrusion. However, a typical premises security alarm employs the following compo-nents:

- Premises control unit (PCU), Alarm Control Panel (ACP), or simply panel: The "brain" of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions. In modern system, this is typically one or more computer circuit boards inside a metal enclosure, along with a power supply.

- Sensors: Devices which detect intrusions. Sensors may be placed at the perimeter of the protected area, within it, or both. Sensors can detect intruders by a variety of methods, such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances.

- Alerting devices: These indicate an alarm condition. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of intrusion, and potentially scaring off burglars. These devices may also be used to warn occupants of a fire or smoke condition.

- Keypads: Small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically feature indicator lights, a small multi-character display, or both.etc.

- Interconnections between components. This may consist of direct wiring to the control unit, or wireless links with local power supplies.

In addition to the system itself, security alarms are often coupled with a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station. Operators at the station see the signal and take appropriate action, such as contacting property owners, notifying police, or dispatching private security forces. Such signals may be transmitted via dedicated alarm circuits, telephone lines, or the internet.

Explanation

Net present value (NPV) is the 'today' net value that deprives from 'future' cash flow of an invest-ment or a capital purchase. Net Present Value is a helpful tool for assessing the total lifetime value of an investment. Procurement professionals or investors can base on this value to make decision to achieve value for money. Generally, an organisation should select the offer which has the highest NPV among their options. Preferably, the NPV of an capital investment should be positive, which means the investment eventually adds value to the business.

Explanation

The holding cost per day of the beer pallet is equal to 1.50/2=0.75

The beer pallet is stored for 5 days, the total holding cost is: 0.75*5=3.75.

Explanation

Kanban (看板) (signboard or billboard in Japanese) is a scheduling system for lean manufacturing and just-in-time manufacturing (JIT).

Poka-yoke (ポカヨケ, [poka yoke]) is a Japanese term that means "mistake-proofing" or "inadvertent error prevention". A poka-yoke is any mechanism in any process that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.

Kaizen is a concept referring to business activities that continuously improve all functions and involve all employees from the CEO to the assembly line workers. Kaizen (改善) is the Sino-Japanese word for "improvement". Kaizen also applies to processes, such as purchasing and logis-tics, that cross organizational boundaries into the supply chain.

Muda (無駄, on'yomi reading) is a Japanese word meaning "futility; uselessness; wastefulness", and is a key concept in lean process thinking, like the Toyota Production System (TPS) as one of the three types of deviation from optimal allocation of resources (the others being mura and muri). Waste reduction is an effective way to increase profitability.
