the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
This paper describes a stochastic network interdiction model for identifying locations for installing detectors sensitive to nuclear material. A nuclear material smuggler selects a path through a transportation network that maximizes the probability of avoiding detection. An interdictor installs sensors to minimize that maximum probability. This problem is formulated as a bi-level stochastic mi...
This research aims to find a suitable transportation rate formula for bed load. Laboratory experiments were conducted in flume monitoring and measuring the of sediment particles (bed load) which move by jumping, rolling, or sliding within flume. study included two parts. The first part is experimenting using tracking particles' movement analysing images taken camera. measurements that have been...
This paper studies the decision-making problem of raw material ordering and transportation in production enterprises, establishes optimal procurement scheme for enterprises under different conditions based on genetic algorithm multi-objective programming. Firstly, five factors affecting company's are summarized; Secondly, analytic hierarchy process (AHP) is used to determine weight each impact ...
Supply chain management in second half recent century extended so much and in current century this extension is continued. One of the scopes that to be interested is extension and adaptation of production and inventory control policy, under just in time philosophy, for material and production control in supply chain. Hence in this paper we will adapt pull-push CONWIP (constant work in process)...
Today, steel to aluminum joints are used to facilitate transportation and fuel consumption. These joints are applied from nuclear, aerospace and naval to automobile and kitchen industries. According to previous studies fusion welding processes are not suitable methods for these joints, solid-state welding, especially friction stir welding, is a proper way to use for these joints. However, using...
In this paper, an application of real-coded Genetic Algorithm (RCGA) for integer linear programming in a production-transportation problem has been discussed. In this discussion, firstly, the model has been developed under the assumption that a company produces a single commodity in different factories, situated at different places. The raw material cost, production cost as well as marketing co...
