    In this paper, we discussed a literature on blood collection-distribution that based on vehicle routing problem. This problem emergence when the process from collection to stock up must be completed in timely manner. We also modified the mathematical model so that it will suited to general collection of blood. A discussion on its algorithm and solution methods are also pointed out briefly in this paper.

    This project deals with a case study of SALBP in power transformer manufacturing. Some workstations in assembly line experienced bottlenecks, while the others suffered with high idle time. Therefore, four heuristic methods are chosen in order to provide solutions for minimizing number of workstations and improve the bottlenecks simultaneously. In this study, LCR, RPW and LPT are successfully minimized number of workstation from 19 to 16 workstations. Consequently, these solutions affect the layout. On the contrary, SPT able to improve the bottleneck by reducing number of workstations from 19 to 17 without affect the line layout. Therefore, this has created an option for engineer to decide which decision should be implement to the assembly line due to enhance the line efficiency.

    Heuristic method for the modified model of capacitated arc routing problems
    ( 2015)
    Muhamad Hafiz Masran
    The management of waste collection in urban areas is a critical issue for some developing countries especially in Malaysia which requires immediate attention. This study attempts to make an analysis and assessment of the development of the Perlis state waste generation distribution and the optimization of waste collection routes. This thesis describes the architecture design of the mathematical modeling for the mixed graph of Capacitated Arc Routing Problem (MCARP) extended from the Capacitated Arc Routing Problem (CARP). Furthermore, it provides a description of several equations that can be used to obtain efficient collection routes such as capacity vehicles constraint. To get the better result, this study used the existing heuristics method for solving MCARP mathematical modeling. The result shows that the total costs produced are considerably acceptable and are also reasonably improved, although the existing heuristics method do not obtain an optimal solution but in term of the computational time is good and better than other methods for small and intermediate networks especially in the mixed graph problem
