The game theory analysis on covering overall migrant workers by their participation in legal housing reserves

  • Chen, Ai
According to the policies from different provinces and regions, existing problems are analyzed. With the game theory analysis,backgrounds and processes of the policies are imitated based on institution and migrant workers level.On the base of the analysis,some solutions are also proposed which can be beneficial to migrant workers.

Cultural landscapes in Argentina : research, project and representation

  • Pesoa Marcilla, Melisa

This article aims to contribute to the use of the concept "cultural landscape" as a tool for the analysis and development of territorial projects in Argentina. In the first part, we intend to summarize some views on the concept of cultural landscape, about the origin of the term, its diffusion and the possibilities and paradoxes that it implies. In the second part, we discuss the way in which this concept becomes a project tool, while in the third part, we highlight the central role that drawing has in the analysis and project. In the fourth part, we present two case study that illustrate the problems we enunciate in the preceding sections. Finally, the conclusions take up the possibilities, challenges and paradoxes of this way of projecting in which the detailed study of the identity of the territory makes it possible to find a way to manage it in a way that reverts to local development., Peer Reviewed

Based on elasticity theory, we use numerical Galerkin finite element discretization method and implement Matlab finite element code to simulate “stress shadow” distributions of mutual orthogonal fractures. The principal stress and principal distributions have the symmetry characteristic on the intersection (coordinate origin). The relationships between stress shadow and flow pressure ratio, pore pressure, fluid pressure and horizontal stress contract are analyzed, respectively. By these techniques of variable displacement construction, changing the viscosity of the fracturing fluid, exploitation of oil and gas wells changing pump rate and fracturing fluid viscosity, reducing pore pressure and increasing the injection volume, taking the advantages of shadow effect, it is likely to produce a complex fracture network., Peer Reviewed

Scheduling and sequencing problem of mix-model-assembly-line (RID:A329)

Mixed Model Assembly Line is the general trend of the automobile industry in our country. The scheduling and sequencing problem is the key technology of the assembly line. Toyota (Japan) production system admits workers to stop the conveyor whenever they fail to finish the operation within their work station in a mixed model assembly line, so, the conveyor stoppage is an important subject in sequencing problem for mixed model assembly line in the Toyota production system. According to this subject, its object of the industrial organization policy is minimizing the total conveyor stoppage time. While in the mixed model assembly line of the United Stated, if the worker is not able to finish the work piece when he arrives the end position, he returns to the start station, leaving the unfinished work piece to be done by the auxiliary worker. In this situation, the object of the industry organization policy of the mixed model assembly line in the United States which is quite different from that of Japan is minimizing the unfinished work load. Studying on the industry theory of the United States, this paper aims at minimizing the utility time (the time used by the auxiliary worker for completing the unfinished work piece), idle time (the time used for the worker is kept for waiting for a work piece to enter the boundary of his allowable work area) and the cost of production under the conditions of different lengths of the assembly line. This paper also studies the relationship between the number of stations, different models of the work pieces needed to process and the time calculated by the computer. One of the results of this paper is when other conditions of the mixed model assembly line (for example, the number of work pieces, the number of stations, the kind of different work piece models, etc.) are settled, the idle time, utility time and the cost of the idle time, utility time are decreased with the increasing of the length of the line (within the length of 15m and 22m). This paper uses the algorithm of Branch and Bound for finding the optimal sequencing of the assembly line. Results show that the algorithm of Brunch and Bound is a useful method for finding the optimal results, but it is not suitable for large scale and complicated assembly lines. So, for large scale mixed model assembly line with numerous of work stations and kinds of work pieces, new and more practiced algorithms for example Genetic Algorithm (GA) and Simulated Annealing Algorithm (SAA) are needed to be used.
