The performances of light-weight and the anti-damage are a pair of conflicting optimization goals. Basing on the damage data of explosion simulation, it studies multi-objective optimization of cantilever box girder about lightweight and anti-damage. Firstly, the method of PCA is introduced to mine the damage data of simulation experiments. Secondly -- the regression function about the damage of cantilever...
In this paper, we deal with the vehicle routing problem where vehicles have finite capacities and demands of customers are uncertain. We represent the uncertain demands by fuzziness and interpret them as possibility distributions. According to the same consideration as the fuzzy programming with recourse, we treat the influence of the fuzzy of customers' demands as recourse cost. Defining the fuzzy...
This paper proposes a novel method of reactive scheduling of job processing for non-disruptive cell manufacturing systems (CMS) against unexpected machine breakdown occurrence. Reactive scheduling problem for reassigning pending jobs in CMS is formulated as a discrete optimization problem of Mixed Integer Programming (MIP) and effective solving method of BPSO-SA which is hybridizing method of Binary...
Distributed manufacturing system has steadily becoming more significant for topics for researchers within manufacturing industry. It is due to the reason that it could provide higher flexibility for an organization to cope with a demanding and fluctuating market. This paper proposes distributed task assignment mechanism for multi-load Automated Guided Vehicle (AGV) operation in manufacturing industry...
The paper is presented an approach of preventive maintenance that improves and enhances downside production efficiencies based on the non-stop maintenance. The approach focuses on reconfiguration and rerouting; besides, to prepare alternative configurations according to different reliability for each machine. In addition reliable probability of machines, there exist critical factors such as...
