Level Scheduling for batched JIT supplyFlexible Services and Manufacturing Journal - - 2010
Nils Boysen, Malte Fliedner, Armin Scholl
A mixed-model assembly line requires the solution of a short-term sequencing problem which decides on the succession of different models launched down the line. A famous solution approach stemming from the Toyota Production System is the so-called Level Scheduling, which aims at distributing the part consumption induced by the model sequence evenly over time. Traditional Level Scheduling seeks to ...... hiện toàn bộ
An efficient hybridized genetic algorithm architecture for the flexible job shop scheduling problemFlexible Services and Manufacturing Journal - Tập 23 - Trang 64-85 - 2010
Nasr Al-Hinai, T. Y. ElMekkawy
The work presented in this paper proposes hybridized genetic algorithm architecture for the Flexible Job Shop Scheduling Problem (FJSP). The efficiency of the genetic algorithm is enhanced by integrating it with an initial population generation algorithm and a local search method. The usefulness of the proposed methodology is illustrated with the aid of an extensive computational study on 184 benc...... hiện toàn bộ
Performance analysis of a drop-swap terminal to mitigate truck congestion at chemical sitesFlexible Services and Manufacturing Journal - Tập 35 - Trang 416-454 - 2021
Budhi S. Wibowo, Jan C. Fransoo
Truck congestion at chemical sites is a persistent problem that is difficult to solve, even using a truck appointment system. This study presents an alternative solution to improve the flexibility of chemical sites by creating a drop-swap terminal adjacent to the site location. The terminal serves as an intermediate depot where the trucks can drop empty containers and swap them with preloaded cont...... hiện toàn bộ
Design of single assembly line for the delayed differentiation of product variantsFlexible Services and Manufacturing Journal - Tập 22 - Trang 163-182 - 2011
Tarek AlGeddawy, Hoda ElMaraghy
Delayed Product Differentiation (DPD) can reduce the manufacturing complexities arising due to the proliferation of products variety. A new optimization model constructs the optimum layout of delayed differentiation assembly lines for a mix of products to be manufactured by the same system and optimizes the position of the differentiation points. This model employs a classification tool (Cladistic...... hiện toàn bộ
Level scheduling under limited resequencing flexibilityFlexible Services and Manufacturing Journal - Tập 22 - Trang 236-257 - 2010
Nils Boysen, Malte Fliedner, Armin Scholl
A mixed-model assembly line requires the solution of a short-term sequencing problem, which decides on the succession of different models launched down the line. A famous solution approach stemming from the Toyota Production System is the so-called Level Scheduling (LS), which aims to distribute the part consumption induced by a model sequence evenly over the planning horizon. LS attracted a multi...... hiện toàn bộ
Continuous-time scheduling of production, distribution and sales in photovoltaic supply chains with declining pricesFlexible Services and Manufacturing Journal - Tập 32 - Trang 629-667 - 2019
Wolfgang Albrecht, Martin Steinrücke
Supply chain networks in the photovoltaic sector were faced with a rapid decline in prices during the past few years, which is predicted to go on in the following years. These circumstances force related companies to coordinate production, distribution and transportation planning of all their network sites thoroughly. Moreover, continuous-time scheduling of processes is required to determine times...... hiện toàn bộ
