Describe the productivity cycle. How does the elements of productivity cycle can be measured?

Draw a project network, determine the critical path, project completion time, find the total float and free float for each activity shown in Table 6(b).

Table 6(b)

A manufacturing firm produces two products. Each product must go through an assembly process and a finishing process. The product is then transferred to the warehouse, which has space for only a limited number of items. The following linear programming model has been developed for determining the quantity of each product to produce in order to maximize profit:

$$
\text{Maximize } Z = 30x_1 + 70x_2 \text{ (profit, $)}
$$
$$\text{Subject to } 4x_1 + 10x_2 \leq 80 \text{ (assembly, hours)}$$
$$14x_1 + 8x_2 \leq 112 \text{ (finishing, hours)}$$
$$x_1 + x_2 \leq 10 \text{ (inventory, hours)}$$
$$x_1, x_2 \geq 0$$

Solve the problem graphically

Consider the information of the following table:

(i) Draw the appropriate network, (ii) Calculate ET and LT of each activity, (iii) Find the critical path, and (iv) Calculate FF for each activity

Discuss factors affecting the selection of materials handling equipment in a production shop.

What are the three time estimates used with PERT?

Task time estimates for a production line setup project at Robert Klassen's Ontario factory are as follows:

(i) Draw the project network.
(ii) Identify the critical path by calculating TF of each activity.
(iii) What is the expected project length?

When an accounting firm audits a corporation, the first phase of the audit involves obtaining "knowledge of the business". This phase of the audit requires the activities in bellow Table. Draw the project network and determine the critical path for the network, the total float and free float for each activity.

The plumbing supply company received the following price schedule for a valve from its supplied:

Annual demand is estimated at 6000 valves, and ordering cost at $10 per order. If annual holding cost is 20% of per unit purchase price. What is the best purchase quantity?
