Q

There will be a good deal of uncertainty in demand, prices, exchange rates, and the competitive market over the lifetime of a supply chain network

A

Therefore, building flexibility into SC operations allows the SC to deal with uncertainty in a manner that will maximize profits

Q

Companies have failed to gain from offshoring for two primary reasons

A
  1. focusing exclusively on unit cost rather than total cost when making the offshoring decision.
  2. ignoring critical risk factors.

Q

Discounted Cash Flow (DCF) analysis

Q

DCF analysis is based on the fundamental premise that (based on the time value of money) – a dollar today is worth more than a dollar tomorrow

A

because a dollar today may be invested and earn a return in addition to the dollar invested.

Q

The present value of future cash flows is found by using a discount factor.

A

If a dollar today can be invested and earn a rate of return ‘k’ over the next period, an investment of $1 today will result in 1 + k dollars in the next period.

An investor would therefore be indifferent between obtaining $1 in the next period or $1/(1+k) in the current period.

Thus, $1 in the next period is discounted by the

Discount Factor = 1/ (1+k)

to obtain its present value.

Q

A manager makes several decisions when designing a supply chain network. For instance:

A
  • Should the firm sign a long-term contract for warehousing space or get space from the spot market as needed?
  • What should the firm’s mix of long-term and spot market be in the portfolio of transportation capacity?
  • How much capacity should various facilities have? What fraction of this capacity should be flexible?

Q

If uncertainty is ignored, a manager will always sign long-term contracts (because they are typically cheaper) and avoid all flexible or backup capacity (because it is more expensive).

A

Such decisions can hurt the firm, however, if future demand or prices are not as forecast at the time of the deacon.

Q

Bellman’s Principle

A

for any choice of strategy in a given state, the optimal strategy in the next period is the one that is selected if the entire analysis is assumed to begin in the next period.

This principle allows the optimal strategy to be solved in a backward fashion starting at the last period.
Expected future cash flows are discounted back and included in the decision currently under consideration.
The value of the node in period 0 gives the value of the investment, as well as the decisions make during each time period.

Q

Uncertainty in demand and economic factors should be included in the financial evaluation of supply chain design decisions.

A

The inclusion of uncertainty typically decreases the value of rigidity and increases the value of flexibility.

22
Q

The present value of a future stream of cash flows is what that stream

A

is worth in today’s dollars.

23
Q

The process of evaluating the present value of any stream of future cash flows so that management can compare two streams of cash flows in terms of their financial value is

A

discounted cash flow (DCF) analysis.

24
Q

The present value of future cash flow is found by

A

using a discount factor.

25
Q

The discount factor used to obtain the present value of money in the next period where k represents the rate of return is

A

1/(1+k)

26
Q

The rate of return k is also referred to as the

A

discount rate, hurdle rate, and opportunity cost of capital.

27
Q

The net present value (NPV) of a stream of cash flows is equal to

A

the sum of all cash flows for all periods being considered discounted by the rate of return for each period.

28
Q

A negative NPV (net present value) for an option indicates that the option will

A

lose money for the supply chain.

29
Q

The decision with the highest NPV (net present value) will provide a supply chain with

A

the highest financial return.

30
Q

In reality, demand and prices are

A

highly uncertain and likely to fluctuate during the life of any supply chain decision.

31
Q

For a global supply chain, exchange rates and inflation are

A

likely to vary over time in different locations.

32
Q

The binomial representation of uncertainty is based on the assumption that when moving from one period to the next, the value of the underlying factor (such as demand or price)

A

has only two possible outcomes - up or down.

33
Q

in the commonly used multiplicative binomial, it is assumed that the underlying factor

A

moves up by a factor u > 1 with probability p.
or
moves down by a factor d < 1 with probability 1 - p.

34
Q

The multiplicative binomial can be used for factors like demand, price, and exchange rates that cannot become negative because it

A

cannot take on negative values.

35
Q

A logical objection to both the multiplicative and additive binomial is the fact that the underlying factor

A

takes on only one of two possible values at the end of each period.

36
Q

A decision tree is

A

a graphic device used to evaluate decisions under uncertainty.

37
Q

Decision tree analysis is based on Bellman’s principle, which states that for any choice of strategy in a given state,

A

the optimal strategy in the next period is the one that is selected if the entire analysis is assumed to begin in the next period.

38
Q

The first step in decision tree analysis methodology is to

A

identify the duration of each period (month, quarter, etc.) and the number of periods T over which the decision is to be evaluated.

39
Q

The last step in decision tree analysis methodology is to

A

start at period T, work back to Period 0, identifying the optimal decision and the expected cash flows at each step. Expected cash flows at each step in a given period should be discounted back when included in the previous period.

40
Q

Uncertainty in demand and economic factors should be included in the financial evaluation of supply chain design decisions, because

A

the inclusion of uncertainty may have a significant impact on this evaluation.

41
Q

Flexibility should be valued by taking into account uncertainty in demand and economic factors. In general, flexibility will tend to

A

increase in value with an increase in uncertainty.

42
Q

A major factor that makes the decision tree methodology quite powerful is

A

the choice of discount rate.

43
Q

The appropriate discount rate used in decision tree methodology

A

should be risk-adjusted and risk may vary by period and decision node.

44
Q

Firms should use simulation for evaluating decisions when

A

Underlying decision trees are very complex and explicit solutions for the underlying decision tree are difficult to obtain.

45
Q

In a complex decision tree there are

A

thousands of possible paths that may result from the first period to the last.

46
Q

Simulation models

A

require a higher setup cost to start and operate compared to decision tree tools.

47
Q

Strategic planning and financial planning

A

should be combined during supply chain network design.

48
Q

The evaluation of supply chain networks

A

should use multiple metrics.

49
Q

Financial analysis should be used as

A

an input to decision making, not as the decision-making process.

50
Q

One of the best ways to speed up the process of financial analysis and arrive at a good decision is to

A

use estimates backed up by sensitivity analysis when it appears that finding a very accurate input would take an inordinate amount of time.

51
Q

The tailored strategy “Focus on low-cost, decentralized capacity for predictable demand” follows which risk mitigation strategy?

A

Increase capacity

52
Q

A labor dispute is a risk driver to be considered during network design. What category does a “labor dispute” belong?

A

Disruptions

53
Q

Simulation methods are very good at evaluating decisions when

A

there are different forms of uncertainty.

54
Q

The textbook mentions that decision makers should design global supply chain networks considering a portfolio of strategic options including

A

the option to wait, build excess capacity, build flexible capacity.
