Production Management (Requested Subject)

1. Production Management concepts in Agricultural Firm in the Philippines.

2. Forecast the supply and demand of swine, chicken and goat in Cagayan Valley, Region 02 for 3 years starting 2013 to 2015.

3. A company which produces refrigeration equipment is attempting to obtain an order for an item which is not one of its standard products but which it has produced in the past. In its bid for the order, the firm will have to state, among other things, the earliest date by which it will be able to deliver the equipment to the customer.

The task of ascertaining this date has been assigned to the firm’s production control department. The department chooses to carry out the task with the aid of the Critical Path Method and, therefore, begins by developing the following data gathering the elements of the project and their time requirements:

 The potential customer has asked that the bid submitted by June 15 and has promised that he will notify the firm on July 1 about whether or not it will receive the order. Hence, July 1 is the earliest date by which manufacturer can start the project. (60 points)

Required:

a.      What will the earliest possible delivery date prove to be? Find this by computing the early start date and the early finish date for each job.

b.     Suppose that the firm receives the order. However, the customer states that because he is not in a position to begin the installation of the requirement before September 15, the requirement should be delivered on that date rather than on August 31. What will be the latest possible start date for the project prove to be? Find this by computing the late start date  and the late finish date for each job.

c.      Calculate the job’s slack times with the use of the information developed in the preceding two parts of this problem.

d.     Ascertain the critical path with the use of the calculated slack times.

4. A farmer owns 500 hectares of land. He must decide how many of those hectares should be developed to the production of one grain and how many to the production of another 

It is estimated that each hectare of grain Y will yield a profit of P20,000.00 and that each hectare of grain H will yield a profit of  P70,000.00.

Grain Y requires 6 labor-hours and 5.5 equipment-hours per hectare, while grain H requires 15 labor-hours and 3.4 equipment-hours per hectare. During the period under consideration, 4,800 labor-hours and 1,400 equipment-hours will be available.

a.      If the farmer insists on utilizing all 500 hectares, how many of them should be devoted to the respective grains? What will be the resultant profit for the period? (15 points)

b.     If the farmer is willing to allow some of the land to lie idle, how many hectares should he devote to the respective grains? What will be the resultant profit for the period? (15 points)

Please submit as early as possible.    thanks!
