浅析水泥熟料生产线的常见问题及优化改造

正水泥,用专业术语表达,是一种粉状水硬性无机胶凝材料。经过加水搅拌后,水泥将成浆体,在空气中硬化或者在水中更好的硬化,并能把砂、石等材料牢固地胶结在一起。长期以来,作为一种重要的胶凝材料,水泥被广泛应用于土木建筑、水利、国防等工程。水泥的生产也备受关注,其中硅酸盐类水泥的生产工艺在水泥生产中最具代表性,是以石灰石和粘土为主要原料,经破碎、配料、磨细制成生料,然后喂入水泥窑中煅烧成熟料,再将熟料加适量石膏(有时还掺加混合材料或外加剂)磨细而成。     

考虑工人行为激励的装配线产出率的实验研究

传统IE模型均基于在制品库存与工人行为互相独立的假设。近来一些学者提出低在制品库存能给工人带来正激励作用。但在对我国一些产品组装类型的民营企业调研中发现,相比低在制品库存装配线,高在制品库存装配线对工人的激励效应更为显著。本文对高在制品库存装配线产生的激励效应提出多个假设,并通过装配线的模拟实验进行了验证,最后进一步研究分析了结论所适用的企业类型。

Between the Ivory Tower and the Academic Assembly Line*

This paper considers the impact of managerialism and the reactions it has engendered in university life. It examines the degree to which institutions of higher education in the UK have in recent years been subjected to what some commentators have seen as a managerial assault, alongside economic pressures to restructure and reform, and explores the reactions of academic and administrative staff in middle and junior levels through a case study of two universities. Consideration is given to attempts to introduce managerial controls, including the setting of targets, appraisals and peer review, as well as to the resistances which followed. It is argued that the notion of resistance to domination and control has been underplayed in the literature of organization and management. In exploring its various manifestations it is shown that managerialism is not fully embedded in university life and that matters are far from settled. It is contended that those engaged in academe in middle and junior levels of the organizational hierarchy are actively seeking to keep alive the craft of scholarship by mediating and moderating the harsher effects of the changes through supportive or transformational styles of working.

Using Simulation and Data Envelopment Analysis to Compare Assembly Line Balancing Solutions

This paper presents a technique for comparing the results of different assembly line balancing strategies by using Data Envelopment Analysis (DEA). Initially, several heuristics--which can be thought of as assembly line balancing strategies--were used to solve seven line-balancing problems. The resulting line balance solutions provided two pieces of information that were of particular interest: the number of workers needed and the amount of equipment needed. These two items were considered inputs for DEA. The different line balance solutions were then used as layouts for simulated production runs. From the simulation experiments, several output performance measures were obtained which were of particular interest and were used as outputs for DEA. The analysis shows that DEA is effective in suggesting which line balancing heuristics are most promising.
