With a focus on (c) and assuming flexibility as a core property that an MIS (Management Information System) should have to make management agile, this study aims to clarify how MIS flexibility could be enhanced. With this aim in mind, the authors will first survey the sources and types of change demands on an MIS and consider in a structured way the flexibility characteristics of an MIS, enhancement of which will conduce to its efficiency in dealing with these change demands. With this groundwork laid, the authors will go on to discuss practical methods to enhance MIS flexibility, and wind up their discussion by presenting the evaluation procedure for this property.展开更多

Therefore, from the design, construction, operation and maintenance stages of the built infrastructural systems; cognizance must be taken of the associated factors and their significance. In considering these indices, the experts will save lots of resources wastage thereby integrating new technologies into the full life cycle of the infrastructure. In this paper, two sets of building infrastructure professionals were assessed. These are the corporate building organization (CBO) and the Operators from two shopping malls within the UK. Thirty-four factors regarding the sustainable building infrastructure appraisal were identified through literature reviews. These characteristics were accordingly classified into two factors (group I and II) and a comparative analysis of their influence conducted. Priority rating of the factors assessment on building infrastructure was through structured, administered survey amongst professionals within these organizations. Information of this survey revealed that the experts maintained a strong concordance in rating these factors. As a result, the associated factors have relatively substantial degree of influence in this context. Further indications of the result in groups I and II are that the CBO experts have indicated the infrastructure size, planning and design as the key factors. Also, the type of building characteristic was among others as the top and bottom marked cases. Similarly, the Operators too have maintained that a proper infrastructure design should incorporate a good policy framework for efficient energy saving fixtures and conservation. Additionally, the installation of quality equipment promotes cost savings of the resources and a just-in-time maintenance of the infrastructure at large. The maintain as-we-go philosophy characteristic was not strongly encouraged in this case.展开更多

A result of deployment of smart meters, with associated equipment, is the electric power industry faced with new and changing threats, vulnerabilities and re-evaluate traditional approaches to cyber security. Protection against emerging cyber-security threats targeting smart meter infrastructures will increase risk to both the utility and customer if not addressed within initial rollouts. This paper will discuss the issues in SMI (smart meter infrastructures) deployments that pertain to cyber security. It will cover topics such as the threats to operations, infrastructure, network and people and organization and their associated risks. SMI deployments include not only the smart meter, but also the interfaces for home energy management systems as well as communication interfaces back to the utility. Utilities must recognize and anticipate the new threat landscape that can attack and compromise the meter and the associated field network collectors. They must also include threats to the WAN (wide-area-network) backhaul networks, smart meter headends, MDMS (meter data management systems) and their interfaces to CIS (customer information systems) and billing and OMS (outage management systems). Lessons learned from SMI implementations from North America, Europe and recently, Japan, will be discussed. How white-box and black-box testing techniques are applied to determine the threat impact to the SMI. Finally, organizational change risk will be discussed and how utilities have responded to re-organizing and developing a security governance structure for the SMI and other smart grid applications.展开更多
