关中麦棉集约式栽培技术模式研究

本试验针对陕西关中棉区气侯特点与种植习惯，研究了夏棉春育、麦林移栽、麦后覆膜等项麦棉集约式两熟栽培技术，扩展夏棉生长的时空和热量条件。三年试验结果表明，在“三密一稀”满幅荷种植的麦田，麦收前育苗移栽、麦后采取覆膜管理等措施，可增加≥15℃有效积温535．6-525．8℃，使夏棉皮棉产量达1197．5～981．0kg·hm^-2。比麦林点播棉籽的一般露地管理夏棉增产皮棉89．4％，较好的解决了当地棉麦两熟栽培有效热量不足的最小限制因子，实现了麦棉集约式两熟作务，提高了土地等资源的利用率。     

Optimal production lot size with process deterioration under an extended inspection policy

A mathematical model to determine the optimal production lot size for a deteriorating production system under an extended product inspection policy is developed. The last-K product inspection policy is considered so that the nonconforming items can be reduced, under which the last K products in a production lot are inspected and the nonconforming items from those inspected are reworked. Consider that the products produced towards the end of a production lot are more likely to be nonconforming, is proposed an extended product inspection policy for a deteriorating production system. That is, in a production lot, product inspections are performed among the middle K1 items and after inspections, all of the last K2 products are directly reworked without inspections. Our objective here is the joint optimization of the production lot size and the corresponding extended inspection policy such that the expected total cost per unit time is minimized. Since there is no closed form expression for our optimal policy, the existence for the optimal production inspection policy and an upper bound for the optimal lot size are obtained. Furthermore, an efficient solution procedure is provided to search for the optimal policy. Finally, numerical examples are given to illustrate the proposed model and indicate that the expected total cost per unit time of our product inspection model is less than that of the last-K inspection policy.

Architecture of Virtual Manufacturing based on Autonomous Manufacturing Islands

Virtual manufacturing (VM) is an integrated synthetic manufacturing environment exercised to enhance all levels of decision and control in a manufacturing networked enterprise. Autonomous manufacturing island (AMI) is an active, dynamic and flexible production cell in the domain of technology, organization and management. This paper explains the concept of VM, proposes the architecture of VM based on AMI and discusses its characteristics. Lastly, a pilot system of virtual manufacturing based on AMI is introduced.
