Improving data quality during ERP implementation based on information product map

ABSTRACT

Poor Data Quality (DQ) is amajor culprit in the failure of ERP implantation. Previous DQ solutions focus more on technical approaches, ignoring the importance of seeking the root causes. Therefore, this paper proposes aprocess-driven DQ monitoring framework by Information Product Map (IPMAP). First, IPMAP is applied to visualizethe manufacturing process of critical information products. Then, the potential deficiencies that may arouse DQ problems are examined from the aspects of process and human. Finally, the corresponding DQ improvement strategies are put forward and validated in case study. The results indicate that the framework provides helpful guidance for promoting ERP DQ.

Management decision-making relating to occupational risks: the role of 'grey data'

This paper reports upon the findings of pilot work research being carried out with the collaboration of a large employer in the UK construction sector. The term 'grey data' is introduced and defined and a pilot grey data review relating to occupational injury risks is described. The results are used as the basis for a preliminary investigation into the utility of grey data in management decision-making relating to occupational risks. Nine factors are identified as important to the managers, these factors falling into two groups, viz. role considerations and subject considerations. It is recommended that future research might investigate the relative importance of these two groups of factors to managers, specifically in relation to occupational risk decision-making.     

烟叶成本控制中数据与单据分离的探索

本文针对烟叶成本控制中数据与单据在时间、控制单元、控制部门等若干层面上的脱节问题,讨论了这种现象对成本控制的不利影响,并对其产生原因和导致的结果进行分析,在此基础上进行了理论对比研究,最后给出了以数据和单据分离传输为主的相应的对策建议。     

The Post-entry Performance of Cohorts of Export Starters in German Manufacturing Industries☆

This paper investigates four cohorts of firms from German manufacturing industries that started to export between 1998 and 2002, and follows them for five years after the start. Export starters are a rare species and small in Germany. Around 30–40% of those starters studied became continuous exporters. The share of total exports contributed by export starters of a cohort is tiny in the start year, and it remains so over the years that follow. Contrary to the market selection hypothesis, there is no evidence that productivity in the start year is systematically related to survival in the export market. There is no evidence of a negative impact of a smaller firm size in the start year on the chance of surviving in the export market. Starting with a higher share of exports in total sales, however, tends to increase the probability of continuing to export.

基于引入理想决策单元DEA的公租房配租方法研究

摇号是目前重庆公租房分配的唯一形式,由于不能区分谁更迫切地需要公租房的问题,不能更好地解决分配公平的问题,本文在建立申请人状况的评价指标系统基础上,采用引入理想决策单元的数据包络分析模型,考虑申请人的困难状况对申请人进行评价和排序,以比摇号更公平的方式分配公租房,这在目前公租房数量较少的情况下有更现实的公平意义.

The Structure of Municipal Water Supply Costs: Application to a Panel of French Local Communities

Network losses and returns are importantissues for water resource management, that are addressed in thispaper by modeling the structure of production for municipal waterutilities with two outputs: water sold to final customers andwater network losses. We propose a measure of economies of scopeto assess the benefit associated with joint production of waterfor final customers and water losses, and several measures ofreturns to evaluate potential gains in exploiting technologicalflexibility of water networks. We estimate the cost structureof water utilities using a GMM procedure with a Translog costfunction and panel data. Estimation results reveal a positivedegree of economies of scope, and short-run returns to productiondensity and returns to customer density that are not significantlydifferent from 1. Significant economies of scale indicate thatlocal communities may benefit from merging into water districts.
