Aiming at the problems of irrational allocation resources, low efficiency caused by unbalanced production line layout, and slow upgrade smart factory, this paper builds a real physical factory platform through optimal control strategy uses GRAFCET algorithm to optimize logistics scheduling during actual system operation. The genetic is used layout effect line; digital twin technology provide pr...

The increasing use of unconventional feedstuffs in chicken's diets results in the substitution of starch by lipids as the main dietary energy source. To evaluate the responses of genetically fat or lean chickens to these diets, males of two experimental lines divergently selected for abdominal fat content were fed isocaloric, isonitrogenous diets with either high lipid (80 g/kg), high fiber (64...

In today’s turbulent environment, companies are faced with two principal challenges. On the one hand, it is necessary to produce ever more cost-effectively to remain competitive. On the other hand, factories need to be transformable in order to manage unpredictable changes in the corporate environment. To deal with these different challenges, companies use the philosophy of lean production in t...

The proponents of lean production have pointed to the positive effects of the work organization on employees in terms of autonomy, enhanced skills and empowerment mainly by their participation into the continuous improvement of work process. But studies that have examined this issue suggest that the increase in autonomy is not sufficient to compensate for increases work intensity. Participatory...

With a review by Dr. Jeffrey Liker, noted lean management expert and best-selling author: “I believe there is a real need for papers like yours... ...The methodology you illustrate through value stream mapping, re-layout, and planning overall flow is the right approach and labs need to see the real example you describe to understand what is possible.” Jeffrey K. Liker Professor of Industrial an...

Lines of mice have been developed in our laboratory by divergent long-term selection for body fat content. This has resulted in a fivefold (23% vs 4%) higher fat percentage in the Fat line at 14 weeks of age, with little difference between the Fat and Lean lines in fat-free body weight. As part of an approach to characterize the physiological mechanisms underlying these different phenotypes, ne...

The assembly line balancing problem is a non deterministic polynomial type planning problem for mass production. Layout design changes constitute a major decision that yields investment for assembly operations and numerous heuristics have been reported in the literature for solving the line balancing problems. U-shaped assembly layout offers several benefits over traditional straight-line layou...

This paper explores the relationship between simulation and the emerging topics of Lean Thinking and lean construction. The ideas which have motivated the evolution of lean construction concepts are presented. The use of simulation as a means of evaluating the benefit of using lean construction techniques is discussed. Two examples of lean thinking based re-design of common construction process...
