The paper describes how logistic influence process in the firm, also there is a comparation with other firms in automobile section. And second part describes a case study of job scheduling in a mechanical-engineering production, the goal is to minimise the overall processing time. The production jobs are processed by machines. This problem is treated as a hybrid five-stage flow-shop. In other words, the job-processing job consists of maximum five tasks, it depends on product, because there is 12 products, each has own production flow. It is a new type of flow-shop in which the first-stage scheduling depends upon the time scheduling of the second stage, and so on. A mathematical model and a heuristic method is formulated, The problem is the NP hardness. The case study is solved with the heuristic method and the solution achieved represents a 10% reduction of the processing time for the given set of jobs.
