63 TRANSPORTATION PROBLEMS 63.1 INTRODUCTION A scooter production company produces scooters at the units situated at various places (called origins) and supplies them to the places where the depot (called destination) are situated. Here the availability as well as requirements of the various depots are finite and constitute the limited resources. This type of problem is known as distribution or transportation problem in which the key idea is to minimize the cost or the time of transportation

Statistical Process Control: A process that monitors standards by take measurements and corrective action as needed. It is in control when only variation is natural‚ if variation is assignable then discover cause eliminate it. Take samples to inspect/ measure- reduce inspection time‚ reduce opportunity of bad quality. Control charts graph of process data over time-show natural and assignable causes. Control charts for variable data (characteristic that is measured‚ length‚height‚ etc) are X-chart

becoming more complex in order to improve the productivity and the flexibility of the production operations. Various planning models are used to develop optimized plans that meet the demand at minimum cost or fill the demand at maximized profit. These optimization problems differ because of the differences in the manufacturing and market context. Most managers find that existing production planning models are not being implemented in practice [1]. A major problem with existing models is the lack of information

to meet changing conditions. 4. It highlights the bottlenecks in the production processes. 5. As the problem is linear in nature the computational power required is less compared to non-linear methods. Therefore‚ large problems like optimization of an entire refinery can be performed using LP technique using desk top computers. 3. Solve the following Assignment Problem |Operations |
