interdiction scenario with his limited resources in order to minimize the covering of the demand points. A bi-level formulation is presented to model this two-player game problem. To solve this problem we use a combination of exact linear programming optimization technique and comprehensive enumeration. To reduce the computing time a heuristic approach based on local search is proposed. Keywords: Maximal Covering Location Problem (MCLP)‚ Multi- level interdiction‚ Fortification‚ Dummy facility 1.

In this writing I will be looking into the different theories which I have learned in the class of mathematical education one. Each theory called out‚ its own believes and developed the less emphasized areas of the previous theory and there are also situations where the theorists argue saying his view for the theory is the best.

Formulate this problem. Answer: (a) Linear programming focuses on obtaining the best possible output (or a set of outputs) from a given set of limited resources. The LPP is a class of mathematical programming where the functions representing the objectives and the constraints are linear. Optimization refers to the maximization or minimization of the objective functions. You can define the general linear programming model as follows: Maximize or Minimize Z = c1 x1 + c2 x2 +………….. +cn xn

The objective of a process control system is to provide a statistical signal when assignable causes of variation are present “ if you can’t describe and measure it the you can’t control or improve it.” SPC a process used to monitor standards by taking measurements and corrective action as a product or service is being produced. Control chart a graphical presentation of process data over time. A process is said to be orperating in SC when only source of variation is common(natural) causes. The process
