Alternative Process Model for Optimization of Dynamic Cellular Facility Layout
This paper addresses a Quadratic Assignment Problem (QAP) model for the Dynamic Cellular Facility Layout Problem (DCFLP) that leads to effective utilization of resources, minimum throughput time, and reduction in material handling, considering alternative process routes for part types. The proposed model objectively allocates resources to manufacturing cells, evolving an optimal facility layout for multi-period dynamic production. The NP-hard (Non-Deterministic Polynomial-Time Hardness) QAP model for the DCFLP is difficult to solve using the conventional method of optimization in a reasonable time span. A Genetic Simulated Annealing (GSA) algorithm -based heuristic approach is developed to explore the four-dimensional search space (Machines-Parts-Workers-Location) of DCFLP in a reasonable time. The algorithm is capable enough to deal with any configuration of layout type with ease in grid pattern (Horizontal line, Vertical columns, U-Shape Layout and Circular Shape Layout), evolving an optimal cellular facility layout in multi- period dynamic production. The comparative results of metaheuristics (Genetic Algorithm (GA), Simulated Annealing (SA) and GSA) for the randomly generated instances substantiate the efficacy of the proposed model.
Consumers' Awareness and Inclination Towards Eco-Friendly Cars with Reference to Sustainable Development
With global warming and health concerns on the rise, there is a surging demand for eco-friendly vehicles across the world. The holistic transition from conventional vehicles to electric cars is crucial for advancing sustainable development. This study seeks to analyze the factors that influence consumers in their choice of cars, their awareness level, perception towards eco-friendly cars, and also the interrelationship among the factors and the extent of their dependability on each other. It concentrates on understanding the association between several demographic factors and the various attributes of environment-friendly cars and their acceptability in the market.
Informational Integration, Relational Integration and Flexibility of LSPs in Transition Economies: Case of Vietnam
Logistics Service Providers (LSPs) play an important role in the national and global supply chains by contributing to the promotion and development of export economies, including Vietnam. Vietnamese logistics firms face very strong competition from foreign entities, which requires them to constantly improve and enhance their competitiveness. To that end, LSPs have evolved from basic service providers such as freight transportation to integrated services to meet all customer needs. The purpose of this paper is to evaluate the relationship between the capability to integrate resources with the flexibility of the LSP in the context of supply chain integration. Data collected from 151 managers of Vietnamese LSPs show that there is a positive impact of informational integration capability and relational integration capability on their flexibility in providing services to customers.
