The development of Chinese coal enterprises has been restricted by the absence of drive on institution and a general strategic planning and the lack of features and innovations in form when developing circular economy. In this paper, the idea of flexibly developing circular economy has been put forward in order to adapt to the complicated and volatile maket. First of all, the flexibly developing capacity...
With the rapid economic development, the level of energy utilization is raising quickly, which results in a series of environmental problems. Urban ecosystem, as the major consumer of energy and key point of environmental pollution control, has to carry out environmental performance evaluation in energy utilization to reconcile the economic growth with ecological preservation. This paper aims at providing...
In this paper, the nonlinear stochastic dynamical system of batch fermentation is investigated in the process of glycerol bio-dissimilation to 1,3-propanediol by klebsiella pneumoniae. Both the patterns of microbial growth and metabolism and formation of fermentation products are strongly effected by bioreactor conditions and fermentation control. Bioreactor conditions and some operations in culture...
In this paper, the hot strip mill batch planning problem is summed as a Prize Collecting Vehicle Routing Problem (PCVRP). According to the hot-milling technical rules, the inverse bounce of the width and the thickness of the steel strips are considered, the inverse bounce penalty table is designed and an improved multi-objective mathematics programming model is presented. To solve this problem, the...
