Regression testing is challenging, yet essential, for maintaining evolving complex soft- ware. Efficient regression that minimizes the time and maximizes detection of faults in great demand fast-paced software develop- ment. Many research studies have been proposed selecting tests under a constraint. This paper presents new approach first evaluates fault detectability each test based on extent ...

In this research, a bi-objective model is developed to deal with a supply chain including multiple suppliers, multiple manufacturers, and multiple customers, addressing a multi-site, multi-period, multi-product aggregate production planning (APP) problem. This bi-objective model aims to minimize the total cost of supply chain including inventory costs, manufacturing costs, work force costs, hir...

This paper develops an energy management approach for a multi-microgrid (MMG) taking into account multiple objectives involving plug-in electric vehicle (PEV), photovoltaic (PV) power, and a distribution static compensator (DSTATCOM) to improve power provision sharing. In the proposed approach, there is a pool of fuzzy microgrids granules that they compete with each other to prolong their lives...

The satellites scheduling mission play an effective role in enhancing the of ground station control and monitoring systems. In this search, SGSEO is re-formulated into a multi-objective optimization task. Therefore, Gravitational Search Algorithm GSA exploited to attain several essential objectives for generating tight scheduling. Moreover, particle swarm model PSO consolidated with novel form ...

Abstract The space inside the capsule such as station sky and core module is narrow, size of depth large, bearing points are scattered weak, there some difficulties in loading, large size, different shape, complicated interface, position, difficult position pose adjustment, high assembly risk, etc.. To solve these problems, a six-DOF heavy-duty robot proposed this paper. adopts combination line...

investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. the process begins with the manufacture of wax patterns. the dimensional accuracy of the model affects the quality of the finished part. the present study investigated the control and optimization of dimensional deviations in wax patterns. a mold for an h-shaped wax pattern was ...
