Many researchers have done research on information systems before; this is because of the breadth of studies or topics about IS. There is some example of a study on how to measure Information System Success by testing instrument factors. Some researchers can produce different judgments regarding the success of implementation of IS; this is because the first definition of success of each researcher is changed, the two perspectives on success assessment, the three variables used, the four implementations in different environments. Several models can be used as references to assess the success of IS, Delone and McLean are examples that are widely used as references, which use six variables in measuring IS implementation. From the model used, later there will be a gap in determining the model, and this becomes an opportunity for the development of the model as follows. The development of models to measure information system success can be done by adoption, adaptation, and combination. This is legitimately valid as long as the development of the model is accompanied by supporting theories. The purpose of this review literature is especially researchers can provide an overview of related to the method of previous researchers. Then it can be used as a framework for solving problems.
Traveling salesman problem (TSP) is the problem of a salesman to visit the city of each city connected to each other and there is the weight of travel between the cities so as to form a complete weighted graph. Departing from a certain initial city, a salesman had to visit (n-1) another city exactly once and return on the initial city of departure. The purpose of TSP is to find the route of all cities with minimum total weight.Many algorithms have been found to solve the TSP, one of which is the Cheapest Insertion Heuristic (CIH) algorithm in the process of inserting weighted steps obtained from the equation c (i, k, j) = d (i, k) + d (k, j)-d (i, j). This algorithm provides different travel routes depending on the order of insertion of cities on the subtour in question.In this final project, the writer took the problem of distribution route of mineral water of al-ma'some 240 ml cup type, with vehicle capacity to meet 1200 carton and have different customer / agent demand that is the distance of depot and agent far from each other, distribution costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
