Explanation

Delphi method was developed in the 1950s, originally to forecast the impact of technology on warfare. The method entails a group of experts who anonymously reply to questionnaires and subsequently receive feedback in the form of a statistical representation of the "group response," after which the process repeats itself. The goal is to reduce the range of responses and arrive at something closer to expert consensus. The Delphi Method has been widely adopted and is still in use today. Delphi method is a subjective forecasting technique

Holt-Winters forecasting is a way to model and predict the behavior of a sequence of values over time—a time series. Holt-Winters is one of the most popular forecasting techniques for time series. It’s decades old, but it’s still ubiquitous in many applications, including monitoring, where it’s used for purposes such as anomaly detection and capacity planning.

Time series analysis is a statistical technique that deals with time series data, or trend analysis. Time series data means that data is in a series of particular time periods or intervals.

Objective forecasting approaches are quantitative in nature and lend themselves well to an abun-dance of data. There are three categories of objective forecasting methods: time series, caus-al/econometric, and artificial intelligence.

Explanation

Holding extra stocks will always improve customer service levels, or at least reduce the risk of them falling. This implies that if an organisation aims at higher service levels, they should have larger safety stock. However, increasing safety stock is not the only solution to improve service level. The widespread adoption of just-in-time (JIT) techniques particularly in the automotive industry has greatly reduced costs with increased service levels as well as the additional benefit of increased problem visibility.

The correct answer should be 'A safety stock is not always required to achieve a required service level'.

Explanation

Net present value (NPV) is the 'today' net value that deprives from 'future' cash flow of an invest-ment or a capital purchase.

The following formula is used to calculate NPV

Where:

Rt is the net cash flow (cash inflow - cash outflow) during the period t

i is the discount rate

t is the number of time periods

As you can conclude from the above formula, the net present value increases when the numerators (net cash flows) increase and/or denominators (1+i) decrease. So the correct answer should be "Net cash flow during a time period increases"

The purpose of this exercise is to help you identify the factors that influence the net present value and how to increase/decrease NPV in real-world scenario.

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

Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities.

MRP process is described in the graph below:
