Document Content and Description Below

A transportation company has signed contracts with a big customer for transporting to him ammunitions, weapons and drugs. The customer has agreed to receive all quantities transferred to him Density (... kilos/cubic palm) Profit (e/kg) Ammunitions 30 0.20 Weapons 40 0.30 Drugs 20 0.10 The company uses two planes. Plane A cannot transport more than 15 tons neither more than 0.1 m3 of cargo. Plane B cannot transport more than 25 tons and over 0.2 m3 of cargo. There is one more restriction: no more than 100 kg of drugs can be transported in each delivery (the delivery includes two flights, one of plane A and one of plane B). Formulate - with all the necessary documentation - the appropriate model to solve this problem. Comment also on which unit is appropriate to be represented the decision variables of the problem.The two main products of a company are manufactured in a production line of three machines, M1, M2 and M3. Each of them operates 7 hours daily on a five-day basis. The unit production cost is e 160 and e 250 respectively, while the corresponding profit rates are 20% and 24%. The durations of the production processes (expressed in seconds) are shown in the following table M1 M2 M3 M2 or M3 Product A 25 30 50 Product B 40 15 40 20 The first product is completed in three phases, while the second one is required to pass a fourth phase, which can be performed either by machine M2 or machine M3. The problem which the company faces is to identify the units that must be produced by each product to maximize the weekly net profit. Design (variables - function - constraints) the appropriate linear programming model to solve [Show More]
