关于提高脱盐水产量及降低电导率的措施

从降低成本消耗找出生产线对脱盐水水质要求的界限值,从提高脱盐水产量及电导率这两个方法分别作了实验。
　　实验一：提高脱盐水产量
　　本实验分三个方面，第一个方面单独对阳床从2.0~2.4米3/小时的流量进行实验，可以得出阳床提高流量出水水质的变化；第二个方面单独运行阴床和混床从2.0~2.4米3/小时的流量进行实验，可以得出阴床和混床提高流量出水水质的变化；第三个方面将以上两个方面整体运行。     

床品追求文化与科技的融合

如今大大小小的床品企业希望通过彰显时尚性、科技性、创意性、生态性、功能性五大特性,在嘈杂的市场里"杀出"一条生路。不过,老话还要重提:围绕床品发生的故事再多,若没有质量撑着,也不过是浮云罢了。十年前,能买床保暖被就是很潮流的事情。十年后,消费者变得挑剔了,要挑花型和花色以彰显时尚;买四件套也到专卖店讲究体验;床品选择要和整体家居相匹配;环保低碳也成为他们的口头禅。

Hospitals: The Market for Health Care Facilities

Health care facilities include hospitals and nursing homes. Demand for beds and occupancy depends on income, prices and insurer restrictions. The supply of beds is limited by regulatory certificates of need. The implied equilibrium vacancy leads to a trade-off with rate increases. Rate increases establish an asset price for a hospital bed. If prices of health care rise faster than income and nonhealth prices, patients demand less bed availability and occupancy. Rising vacancy and rising prices occur, consistent with the empirical observations for U.S. health care facilities. For 1980–2001, the equilibrium vacancy rate for U.S. hospitals is between 27% and 36% depending on capacity adjustments, bed availability and price expectations. Equilibrium vacancy is near the actual rate after 2000, but that rate is 11 percentage points higher than in the early 1980s when the number of beds was nearly one-third higher. Usually rent regulation leads to excess demand. But in a general equilibrium model with income, relative prices, expectations, supply and capital markets, price regulation can coexist with excess supply.

STRATEGY AND CONTROL IN SUPPLIER–DISTRIBUTOR RELATIONSHIPS: AN AGENCY PERSPECTIVE

This paper examines the influence of competitive strategy on the relationship between suppliers and their distribution networks. Drawing on agency theory, hypotheses are developed specifying the appropriate match between manufacturer strategies and systems of control within distribution channels. Cluster analysis is used to show distinct differences in channel management and structure for the three generic strategies of cost leadership, differentiation and focus. Results suggest that variation in control relationships may be explained by the demands posed by manufacturers' competitive strategies. This study therefore extends the applicability of Porter's typology to the specific structure of distribution channels and shows that agency theory can provide insights into the economic basis of interorganizational relationships.     

Developing an expert system on project evaluation: Pt II: Structuring the system

The work here described is the early stages of a programme to develop a series of Expert Systems (ES's) in the management of R&D. In particular, the development of a prototype ES using a package program Crystal Ver. 2.1 is the focus together with the problems encountered. The literature had suggested that the use of such packages facilitated the process for those exploring ES's. What was not clear from the literature or the program manuals was the limited range of problems which could be handled. The programs have a rigid structure such that unless the logic of the problem solving process matches that of the program, severe difficulties will ensue. This paper outlines the inherent structure of the programs and indicates the kind of problems which would fit. Specific problems which were encountered when trying to stretch the use of the program are explained in detail. It goes on to explain how these problems were got round using Lotus 1–2–3 which proved far more flexible in practice. This kind of understanding is essential if ES's are to become every-day tools of R&D management. The objective in developing the Expert System (ES) was for it to be advisory to those preparing project proposals for possible submission to higher management within the context of an R&D laboratory. Thus the intention was to capture the expertise of senior managers, make it available to more junior ones, and thereby improve the quality of their work. This concept proved to be naive in that the expertise proved to be so diffuse that a wholly new rationale to structure the expertise had to be developed. This process, the subsequent development into a prototype ES, and its evaluation, have already been published (Wilkinson, 1991). The literature on ES's had suggested that the use of available package programs was straight forward and that the real problem was in establishing the expertise to be used and in structuring it to fit the program. This too proved to be an over-simplification. When this work started, the exact nature of the package programs had not been spelt out adequately. The purpose of this paper, Part II, is to describe their inherent structure and the limitations which this imposes on the kind of problems for which they can be used. The insights gained in this work into the evaluation of projects and the inadequacies of previous evaluation techniques will form the contents of Part III of this series of papers.     

ERP system usage: the role of control and empowerment

Organisations have made significant investments in enterprise resource planning (ERP) systems with the strategic expectation that employees will utilise this technology to enhance organisational performance. However, research indicates that ERP systems are underutilised. In order to disentangle the challenge of underutilisation, this paper addresses the impact of organisational control and empowerment on infusion—the deep and comprehensive usage of an information system. Moreover, it also tests whether infusion will lead to higher levels of ERP system success. Data from a sample of 260 matched pairs of ERP system users and their supervisors were collected and analysed. Results indicate that empowerment is positively related with infusion, whereas an inverted u‐relationship has been found for organisational control. The critical link between infusion and ERP system success was found as well, meaning that the more users utilise the system to its fullest extent, the more likely the organisation is to attain ERP systems' promised benefits.     

COVID-19, economic crises and digitalisation: How algorithmic management became an alternative to automation

The COVID-19 crisis witnessed a major rise in investment in software for the digital organisation and rationalisation of work, while investment in robotics is continuously lagging behind expectations. This article argues that we can understand this development as the continuation of the rise of algorithmic management as a technological fix for profitability crises. Thus, in the face of falling wage rates and a structural overaccumulation of capital since the 1970s, algorithmic management has become an alternative to automation. The article reconstructs the history of algorithmic management in connection to economic crises. This allows for periodisation of the rise of algorithmic management from 'computer-integrated manufacturing' to remote work in four waves. In times of crisis, algorithmic management functions as a substitute for investment in 'tangible capital' such as robots. Structural economic forces thus interact with labour conflicts at the company level, shaping the rise of algorithmic management.
