This paper is a comprehensive and up-to-date review of the existing literature on manufacturing resource planning models under uncertainty. The authors have found that the combined effects/ impacts of the uncertainty factors on the system parameters have yet to be thoroughly studied. So far no research has been conducted into developing mathematical model(s) to study the uncertainty issues holistically in multi-period, multiple product, and multi-stage environments for manufacturing resources planning in association with commonality. OPSOMMING Die primere doel van hierdie artikel is om die insig in vervaardigingshulpbronbeplanning onder onsekerheid te bevorder. Die huidige stand van sake word ondersoek en gapings word uitgewys aan die hand van literatuur beskikbaar in gesaghebbende joernale. Die outeurs bevind in die studie dat die sisteemparameters en die invloed van onsekerheid daarop nog nie voldoende bestudeer is nie. Geen navorsing is nog onderneem om wiskundige modelle te ontwikkel om op holistiese wyse die impak van onsekerheid in multi-periode, veelvoudige produk en multi-stadium omgewing te bestudeer nie.","PeriodicalId":290908,"journal":{"name":"ERN: Process (Topic)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132438822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we compare the levels of heterogeneous beliefs between diversified firms and focused firms. We study the change in the level of heterogeneous beliefs subsequent to diversifying and non-diversifying mergers. We also relate the diversification effect on investors' heterogeneous beliefs to the diversification effect on firm value and ex-post stock returns. We document four findings. First, we find that diversification reduces the level of heterogeneous beliefs on a firm's future prospects. Second, the excess level of heterogeneous beliefs on diversified firms relative to focused firms follows a pattern of mean-reverting. Third, the value of diversified firms increases relative to focused firms with an increase in the diversified firms' excess level of heterogeneous beliefs. Finally, we find that a smaller excess heterogeneity of beliefs on diversified firms is followed by an increase in the diversified firm's ex-post excess values and an increase in their ex-post stock returns. Overall, our results contribute to the understanding about how corporate organization structure affects the heterogeneity of investor beliefs and firm values.","PeriodicalId":290908,"journal":{"name":"ERN: Process (Topic)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Less well understood is the tradeoff between the increased ability to precisely meet customer preferences and the increased leadtime from order placement to delivery often associated with customized products. In this paper, we use a locational customer choice model to formulate a firm's integrated product line design problem that involves variety, leadtime (or inventory), and pricing decisions. We propose a dynamic programming based solution procedure that amounts to solving a shortest path problem on an acyclic network, and derive some structural results on the optimal product line design. We find that unimodal preferences generally result in hybrid product lines, with standard products clustering around the mode and custom products covering the tails, in contrast with the all-custom or all-standard product lines that are optimal under uniform preferences. We also numerically examine how the firm should adjust its leadtime and variety in response to changes in parameters such as customer dispersion and operational scale. We find that the tradeoff between leadtime and variety is sometimes nonintuitive and complex.","PeriodicalId":290908,"journal":{"name":"ERN: Process (Topic)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132034413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These will affect stakeholders with varying perspectives and interests in the system. This is particularly the case in health care, as a feature of this sector is that responsibility of services is shared between many autonomous units. In these and similar settings, it is essential to analyse stakeholders and to understand their expectations and attitudes towards the system. Such an understanding will help implementers to address stakeholder interests and to encourage acceptance. Therefore, the purpose of this paper is to develop a theoretically based model to analyse how stakeholder attitudes and behaviours in a hospital setting affect the outcome of ERP implementation. This model is applied in an empirical study of a project to introduce an ERP system in medium-sized hospital in The Netherlands. The study shows how the ERP implementation impacts the interests of stakeholders such as physicians and administrators, which caused tensions. The paper examines the reasons of these tensions. In doing so, it contributes to our understanding of ERP implementation in health care and any other similar sectors from a stakeholder perspective, and it may help implementers to manage this more effectively.","PeriodicalId":290908,"journal":{"name":"ERN: Process (Topic)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126827224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It argues that the Anti-Money Laundering Law (AMLA) was exogenously driven, as the policy was instigated purely by external demand and enacted under external pressure. AMLA is considered an imposition of the Paris-based intergovernmental organization, the Financial Action Task Force (FATF). The swiftness of the enactment of AMLA exemplifies the immense influence that an international financial organization can have on the policy actors as well as on the policymaking process. The policymaking process in this type of institutional engagement — between institutional actors (executive and legislature) within a polity and an international organization — is efficient in producing a policy output. However, the process represents an issue of international override on a state, as a nonveto player dictates to the institutional veto players. This experience supports the global pattern that, in issues associated with global financial standards, policymaking will less be shaped by the institutional actors and will extensively be defined by international actors. The making of AMLA presents an archetype of how international organizations can hold sway over the state.","PeriodicalId":290908,"journal":{"name":"ERN: Process (Topic)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134588974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
