一种基于语法的供应链流程定义元模型

在供应链流程建模和描述的方法体系中,语法建模方法是最新出现的一种很有发展潜力的建模语言,与其它建模方法相比具有多方面的优越性.供应链流程定义语言(SCPDL,supply chain process definition language)作为一种新的供应链流程建模方法,是供应链流程与语法模型的转换器,它可使供应链流程转化为相应的语法模型,以便在系统上实现对流程的查询、管理等逻辑处理,并进一步实现了不同方法描述的供应链流程之间的便利转换.通过对流程定义语言的深入研究,融入最新的过程语法建模和协调理论的相关理念,提出了一个基于语法的供应链流程定义元模型.并在此基础上采用XML(eXtensible Markup Language)对其规则进行重写,形成了基于XML的供应链流程定义语言.提出的XSCPDL(XML SCPDL)模型方法将使供应链管理的建模、管理和优化工具与供应链流程引擎之间实现相互转换,并便于不同软件开发商提供的流程模型在XML的平台上进行快速交互.

Understanding Organizational Safety Using Value-Focused Thinking

Decision analysis is recognized as the right way to make risk management decisions, using probabilistic techniques to assess the accident risk. It is also accepted that the decisions that individuals in the organization make affect the likelihood of an accident and thus managerial and organizational factors should be included in the risk modeling process. However, decision analytic techniques have not been used to understand the decisions that are made by these individuals. The initial domain for this research is marine transportation. We use the framework of value-focused thinking in order to understand safety decisions made within our research partner organization, a major domestic oil tanker operator. We describe the results of interviews held with managers and employees from this organization. Through these interviews, we sought to understand the values these experts apply in their roles within the organization and the objectives they seek to achieve to contribute to its overall safety performance. The end result is a framework that not only portrays the fundamental objectives of safe operations for various roles in the organization, but also interconnects these different decision contexts. We believe that this approach is fundamentally different from those used in previous work and that this is an interesting application of value-focused thinking.     

Learning,signaling, and convincing: The role of experimentation in the business modeling process

This study examines experimentation in the business modeling process, unpacking three different roles of experimentation: learning, signaling, and convincing. Learning is an inherent role of experimentation, as managers typically experiment to engage with the environment and to obtain knowledge. This study uncovers another set of roles, which have a symbolic nature. These roles show that experimentation is not just a learning process, but also a strategic legitimation process, aimed at enacting the environment. Experimentation serves the purpose of signaling to potential customers and other stakeholders, and of convincing them to embrace the business model. Furthermore, this study shows that experimentation takes two forms—purposeful interactions and experimental projects—and that these forms can support the different roles of experimentation.     

META-DESIGN CONSIDERATIONS IN DEVELOPING MODEL MANAGEMENT SYSTEMS*

This paper examines cognitive considerations in developing model management systems (MMSs). First, two approaches to MMS design are reviewed briefly: one based on database theory and one based on knowledge-representation techniques. Then three major cognitive issues—human limitations, information storage and retrieval, and problem-solving strategies—and their implications for MMS design are discussed. Evidence indicates that automatic modeling, which generates more complicated models by integrating existing models automatically, is a critical function of model management systems. In order to discuss issues pertinent to automatic modeling, a graph-based framework for integrating models is introduced. The framework captures some aspects of the processes by which human beings develop models as route selections on a network of all possible alternatives. Based on this framework, three issues are investigated: (1) What are proper criteria for evaluating a model formulated by an MMS? (2) If more than one criterion is chosen for evaluation, how can evaluations on each of the criteria be combined to get an overall evaluation of the model? (3) When should a model be evaluated? Finally, examples are presented to illustrate various modeling strategies.     

RESOURCE ALLOCATION TO IMPROVE SERVICE QUALITY PERCEPTIONS IN MULTISTAGE SERVICE SYSTEMS

Service quality improvement has become an imperative in today's service firms. In this paper, we present a modeling framework that combines marketing and operations viewpoints for resource allocation. The framework can be used to allocate resources to the different stages of a multistage service system, where the manager's goal is to improve customers' perceptions of service quality, given some budget. Optimal allocation guidelines are provided, and the interplay of three factors on the resulting allocation scheme is captured. These factors are the current level of customers' perceptions of service quality at each stage, the cost of implementing a service quality improvement at each stage, and the importance placed by customers at each stage. Sensitivity analysis to provide additional managerial insights is also performed. We demonstrate the applicability of the modeling framework, using data from a real life health care environment. Model limitations and future research are also discussed.     

Developing Absorptive Capacity Theory for Public Service Organizations: Emerging UK Empirical Evidence

A strong public policy focus on high performance means that utilizing management knowledge effectively is at a premium for UK public service organizations. This study empirically examined two English public agencies to explore the inter‐sectoral transfer of a strategic management model originally developed in the private sector – absorptive capacity – which is one way of conceptualizing an organizational competence in such knowledge mobilization. Two theoretical contributions are made. First, a new absorptive capacity framework for public service organizations is developed which recognizes the participation of public agency project teams during an innovation process proceeding over time with phases of co‐creation, testing, metamorphosis and diffusion. Second, our novel framework modifies an early influential model of absorptive capacity. Counter to this model, we argue that realized absorptive capacity requires agency from skilled and embedded actors to turn ‘curbing routines’ into ‘enabling routines’ in all four stages. Project (middle) managers have flexibility in their roles to seize episodic moments of opportunity to innovate and achieve service delivery goals, and to build absorptive capacity capability. Absorptive capacity capability develops organically over time. Future research directions are discussed.     

Comprehensive planning for libraries

In the area of planning, the literature has been almost entirely concerned with planning in the business (i.e. profit) setting. Some literature does exist on planning in the nonprofit sector, but it usually deals with tactical planning of the short-term character. This is specially true in the area of libraries and many librarians have developed and do administer large, complex organization— where conprehensive, long range planning is almost completely untreated in the literature.The current paper discusses the various steps in the strategic planning process, and relates them to a situation in which comprehensive long range plans for a new health sciences library have been developed, and to a considerable degree, implemented. In this framework, the steps of developing purpose and objecives, forecasting and policy formulation, developing and choosing growth strategy, determining resource requirements and provions, developing an organizational structure, and control system utilization are discussed both in the general framework of comprehensive planning, and with respect to actual experience in the development of a health sciences library. The roles of tactical planning and the implementation of plans are also treated.     

A Public Transportation Decision‐Making Model within a Metropolitan Area

Understanding the decision‐making factors associated with public transportation is essential in strategic development of public transportation to improve acceptance and utilization of mass transit systems. This research analyzes factors affecting attitudes toward public transportation and the choice of transportation mode by investigating the public transportation decision‐making process of working professionals using a survey methodology. The objectives of this research are to model the transportation decision‐making process of public transportation users in a metropolitan area and to determine key factors that affect the public transportation choices made by potential public transportation users. This study contributes to the literature by developing and testing an integrated theoretical framework for modeling an individual's public transportation decision‐making process using four independent variables: Perceived Public Transportation Security, Knowledge, Price, and Convenience. We develop the proposed theoretical framework based upon the extant literature and tested it using partial least squares structural equation modeling (PLS‐SEM). Based on the Theory of Reasoned Action, the Theory of Planned Behavior, and utility theory, we develop the factors and refine associated items using confirmatory factor analysis.
