Question
Chapter D, Problem 1DQ
Summary Introduction
Interpretation: The information required to decide whether the management needs to rent a warehouse is to be determined. Also, the ways in which the linear programming model can be helpful is to be determined.
Concept Introduction:When there are more than two variables (behaving linearly) in a problem in which an objective function is to be optimized, the problem can be solved through linear programming. The solution will also indicate the critical and non-critical variables (called constraints). Thus the impact of any variation of the critical constraints can also be assessed.
Expert Solution & Answer
Answer to Problem 1DQ
The inferenceof not taking another warehouse on rent (at whatever rate) can be derived from this model.
Explanation of Solution
Given information:
- Three equal to or less than constraints.
- The two critical constraints of raw material and labour costs.
- Availability of a warehouse at cheap rates.
- The management needs to know whether storage space is a binding constraint. It is not, because the intersection of labour hours and raw materials is the optimal solution.

Trips Logistics, a third-party logistics firm that provides warehousing and other logistics services, is facing a decision regarding the amount of space to lease for the upcoming three-year period. The general manager has forecast that Trips Logistics will need to handle a demand of 100,000 units for each of the next three years. Historically, Trips Logistics has required 1,000 square feet of warehouse space for every 1,000 units of demand. For the purposes of this discussion, the only cost Trips Logistics faces is the cost for the warehouse. Trips Logistics receives revenue of $1.22 for each unit of demand. The general manager must decide whether to sign a three-year lease or obtain warehousing space on the spot market each year. The three-year lease will cost $1 per square foot per year, and the spot market rate is expected to be $1.20 per square foot per year for each of the three years. Trips Logistics has a discount rate of k = 0.1.

The Seaside Hotel is a three-star hotel in Newquay, Cornwall. It contains 108 rooms and employs 30 fulltime and 40 parttime personnel. Between May and August, the hotel's workforce is nearly doubled by casual and temporary workers. Cornwall is a difficult place to do business, especially in the tourism industry. Business is highly seasonal with hotels experiencing very low occupancy during the offseason and many hotels choose not to operate during this time. The Seaside Hotel operates all year round by supplementing its tourism trade during the off-season by offering discounted conferencing facilities for local businesses and as a cheap base for corporate events and activities, such as team building weekends. Tourism is, however, vitally important for the region and its businesses and provides a significant proportion of all jobs in the South West. Cornwall can, however, be a difficult place in which to work. For instance, Newquay – Cornwall’s most popular holiday destination – is one…

Grain grown in southern Manitoba is carried by rail to Churchill during the open-water shipping season. Unfortunately the port is open only 50 days per year during July and August. This leads to some critical crew staffing decisions by management. The port has the capacity to load up to 7 ships simultaneously, provided that each loading bay has an assigned crew. The remote location and short shipping season results in a very high labor cost for each crew assigned, and management would like to minimize the number of crews. Ships arrive in a random pattern that can be modeled using the Poisson probability model. If a ship arrives and all available loading bays are filled, the ship will be delayed, resulting in a large cost that must be paid to the owner of the ship. This penalty was negotiated to encourage ship owners to send their ships to Churchill.Results of an initial analysis…arrow_forward
- Formulate but do not solve the problem.The management of Hartman Rent-A-Car has allocated $2.25 million to buy a fleet of new automobiles consisting of compact, intermediate-size, and full-size cars. Compacts cost $18,000 each, intermediate-size cars cost $27,000 each, and full-size cars cost $36,000 each. If Hartman purchases twice as many compacts as intermediate-size cars and the total number of cars to be purchased is 100, determine how many cars of each type will be purchased. (Assume that the entire budget will be used. Let x, y, and z denote the number of compact, intermediate-sized, and full-size cars purchased, respectively.) = 2,250,000 = x = 100arrow_forwardJerry Wei, the hospital administrator at St. Charles General, must appoint head nurses to four newly established departments: urology, cardiology, orthopedics, and obstetrics. In anticipation of this staffing problem, he had hired four nurses, considered their backgrounds, personalities, and talents, and developed a cost scale ranging from 0 to 100 to be used in the assignment. A 0 for a nurse being assigned to the cardiology unit implies that the nurse would be perfectly suited to that task. A value close to 100, on the other hand, would imply that he or she is not at all suited to head that unit. The accompanying table gives the complete set of cost figures that the hospital administrator feels represented all possible assignments. Which nurse should be assigned to which unit?
