Hybrid Flow Shop Scheduling

This paper considers two stage hybrid flow shop (HFS) with identical parallel machine. The objectives is to determine makespan have been minimized. This paper presented memetic algorithm procedure to solve two stage HFS problems. To evaluated performance of propose method, the results have been compared with two meta-heuristic, genetic algorithm, simulated annealing. The experimental results show that propose method is more effective and efficient than genetic algorithm and simulated annealing to solve two stage HFS scheduling problems.

Historical Origins

This study makes use of Ferdinand Hahn's insights (with Son of God as case study) to indicate how the naming of Jesus developed in stages. It is shown that the name Son of God was not used by Jesus. It functioned within the context of the cultic activities of early Christianity, was taken over from the surrounding religious, political and cultural world while its referential meaning shifted in the various layers. Hahn focuses on the multi-stage development of the Jesus tradition from an Aramaic "Judaism", through  a Hellenistic "Judaism" to a Gaeco-Roman stage. First the possible historical origins of the title Son of God are discussed, after which Hahn's view is taken into consideration.

This paper investigates semi-online scheduling problems on two parallel machines under a grade of service (GoS) provision subject to minimize the makespan. We consider three different semi-online versions with knowing the total processing time of the jobs with higherGoSlevel, knowing the total processing time of the jobs with lowerGoSlevel, or knowing both in advance. Respectively, for the three semi-online versions, we develop algorithms with competitive ratios of3/2,20/13, and4/3which are shown to be optimal.

One of the discussed topics in scheduling problems is Dynamic Flexible Job Shop with Parallel Machines (FDJSPM). Surveys show that this problem because of its concave and nonlinear nature usually has several local optimums. Some of the scheduling problems researchers think that genetic algorithms (GA) are appropriate approach to solve optimization problems of this kind. But researches show that one of the disadvantages of classical genetic algorithms is premature convergence and the probability of trap into the local optimum. Considering these facts, in present research, represented a developed genetic algorithm that its controlling parameters change during algorithm implementation and optimization process. This approach decreases the probability of premature convergence and trap into the local optimum. The several experiments were done show that the priority of proposed procedure of solving in field of the quality of obtained solution and convergence speed toward other present procedure.

Summary Subject and purpose of work: Urban transport is a key element of the functioning of urban agglomerations around the world. As it is of strategic importance, the needs of its users have to be diagnosed. Due to the fact that students are the most numerous social group using public transport, particular attention should be paid to students as the real creators of the needs of urban transport. The paper aims to diagnose the challenges in urban transport shaped by the process of studentification based on the case study of Toruń. Materials and methods: The multi-stage research approach was adopted, among others a survey among students. The choice of the research area was determined by the fact that Toruń is one of the largest academic centres in Poland. Results: Toruń is experiencing the effects of the studentification process in different dimensions, including the spatial and transport facets. Conclusions: The majority of students use public transport, daily or several times a week. The most preferred means of transport is the tram owing to its relative speed and punctuality.
