Concept explainers
A
Interpretation: To maximize the profits for the given constraints and objective function.
Concept Introduction: To obtain the objective function is to maximize or minimize the
B
Interpretation: In linear programming, find the better optimal solution using graphic method.
Concept Introduction: In linear programming, graphic method are used to solve the problems by the point of intersection (higher and lower points) between the objective function and regional value of the graph.
C
Interpretation: To Determine the constraints with slack or surplus.
Concept Introduction: In Linear Programming, some mathematics oriented problem will be solved by slack variable and surplus variable. Slack variables is defined as less than (<) or equal (=) type of constraints to getting the equality constraint. Surplus variables is termed as greater than (>) or equal (=) type of constraints to getting the equality constraint.

- NTS is a Swiss intermodal operator located in Lausanne. When customers need to transport goods between origin and destination, NTS supplies them with one or more empty containers in which the goods can be loaded. Upon arrival at the destination, the goods are unloaded, and the empty containers must be transported to the pickup point for new customers. Therefore, NTS management needs to reallocate empty containers periodically (every week). The company's focus is on the transportation activity of empty containers, which is very expensive (almost 35% of the total operational costs). In May 2023, several empty containers, totaling 20 containers, need to be reallocated among terminals in Amsterdam, Berlin, Munich, Paris, Milan, Barcelona, and Madrid. The available or requested number of empty containers at various terminals is reported, along with the transportation costs (in euros per container) as seen in Figure 1.Determine how to solve the problem with the goal of minimizing…arrow_forwardNTS is a Swiss intermodal operator located in Lausanne.

SVTC is currently evaluating four different approaches to help them maintain their fleet of cars and vans efficiently at the lowest possible cost. Their options are: (1) No preventive maintenance at all and repair vehicle components when they fail; (2) Take oil samples at regular intervals and perform whatever preventive maintenance is indicated by the oil analysis; (3) Perform an oil change on a regular basis on each vehicle and perform repairs when needed; (4) perform oil changes at regular intervals, take oil samples regularly, and perform maintenance repairs as indicated by the sample analysis. Option #1 costs nothing to implement and results in two possible outcomes: There is a .10 probability that a defective component will occur, requiring emergency maintenance at a cost of $1,200, or there is a chance that no defects will occur and no maintenance will be…arrow_forward

It can meet this demand by shipping existing inventory from any of its three warehouses. Warehouse 1 has 400 tons of inventory onhand, Warehouse 2 (W2) has 500 tons, and Warehouse 3 (W3) has 600 tons. The company would like to arrange the shipping for the lowest cost possible, where the per-ton transit costs are as follows: W 1 W 2 W 3 $7.50 $6.75 $6.25 $7.00 $6.50 $8.00 Customer A Customer B Write the objective function and the constraint in equations. Let V;= tons shipped to customer i from warehouse j, and so on. For example, VA1 = tons shipped to customer A from warehouse W1.
