Empirical results are anchored concept integrated periphery and theoretical framework nested structure. We obtained data after a personal meeting General Secretary Association Automotive Industry database contains list 313 suppliers different lev...

Multijob production (MJP) is a class of flexible manufacturing systems, which produces different products within the same system. MJP widely used in product assembly, and efficient scheduling crucial for productivity. Most existing methods are inefficient multijob serial lines with practical constraints. We propose deep reinforcement learning (DRL)-driven framework by properly considering const...

Finding a secure and comfortable parking space is one of the needs automobile owners when they visit retail centers. The ability lot managers to provide information on sufficient capacity access presents barrier delivering facilities in Due this, website-based facility management system required, allowing drivers make reservations payments online based plan shopping center. method used design P...

I study detailed data from eleven automobile assembly plants. These data display considerable cross-plant heterogeneity in production scheduling. To explain the observed heterogeneity, I solve a dynamic programming model. When desired production is below the plant's minimum e$cient scale, non-convexities induce production bunching; the plant uses less than full capital utilization on average an...

The automobile Real-Time Operating System (RTOS) is hard to design and implement due to its real time features and increasing complexity. Some automobile RTOS standards are released aiming at unifying the software architecture of vehicle systems. Most of the standards are presented informally in natural languages, which may lead to not only ambiguities in specifications but also difficulties in...

The Swiss Spallation Neutron Source SINQ of the Paul Scherrer Institute provides neutrons via proton-induced spallation reactions in a lead target. Produced are thermalized and impinge on 235U-targets, enclosed three-part chamber assembly, which is located inner wall shielding. thermal-neutron-induced fission products can be readily transported from this assembly to radiochemical laboratory usi...

This study investigated the relationship between pneumatic nutrunner handle reactions, workstation characteristics, and prevalence of upper limb injuries in an automobile assembly plant. Tool properties (geometry, inertial properties, and motor characteristics), fastener properties, orientation relative to the fastener, and the position of the tool operator (horizontal and vertical distances) w...

The growth of the fleet rolling stock motor transport increases requirements for road safety, which is largely determined by operational reliability and technical condition components mechanisms chassis. In many countries, large-scale studies are being conducted related to problems improving quality, durability vehicles technological equipment based on repair kits, as well manufacturing assembl...

this paper presents a strategy for using harmony search algorithm in facility layout optimization problems. in this paper an adapted harmony search algorithm is developed for solving facility layout optimization problems. this method finds an optimal facility arrangement in an existing layout. two real-world case studies are employed to demonstrate the efficiency of this model. a comparison is ...
