Philosophical and methodological reflection on database capacity planning: a controllership standpoint

This paper analyzes the capacity-planning process of database management systems focusing the theoretical decision models that considers the variables constraints that could be taken slightly and other variable constraints that are indispensable during upgrade. In order to proceed with the aforementioned, we assume that capacity planning decision, which considers the general corporate, technical, users and executive views aiming at prioritizing a measurable relative importance of the planning constraints is capable of giving more economic added-value decision elements to the management. Thus, the optimization multicriteria analysis leads us to infer upon the reasonableness of the decision taken in regard to implementing budgetary planning in moment of business uncertainties. Results of this study indicate that corporate strategic views in decision-taking processes some times override some technical, users and executive views as relating to capacity planning in information technology management environment

Adaptation of coordination mechanisms to network structures

The coordination efficiency of Supply Chain Management is determined by two opposite poles: benefit from improved planning results and associated coordination cost. The centralization grade, applied coordination mechanisms and IT support have influence on both categories. Therefore three reference types are developed and subsequently detailed in business process models for different network structures. In a simulation study the performance of these organization forms are compared in a process plant network. Coordination benefit is observed if the planning mode is altered by means of a demand planning IT tool. Coordination cost is divided into structural and activity-dependent cost. The activity level rises when reactive planning iterations become necessary as a consequence of inconsistencies among planning levels. Some characteristic influence factors are considered to be a reason for uninfeasible planning. In this study the effect of capacity availability and stochastic machine downtimes is investigated in an uncertain demand situation. Results that if the network runs with high overcapacity, central planning is less likely to increase benefit enough to outweigh associated cost. Otherwise, if capacity constraints are crucial, a central planning mode is recommendable. When also unforeseen machine downtimes are low, the use of sophisticated IT tools is most profitablePeer Reviewe

Optimal Strategies for a Knowledge Workers Acquisition Problem with Expanding and Volatile Demand: Train Internally or Recruit Externally?

The aim of this paper is to consider the process of supplying trained workers with knowledge and skills for upcoming business opportunities, and of training apprentices prepared to meet future demands in an IT service firm. As the demand for new workers has fluctuations, a firm should employ a buffer workforce such as apprentices or interns. However, as a result of rapid development of a business, the buffer‟s capacity may be exceeded, thus requiring the company to recruit skilled workers from outside the firm. It is thus important for a firm to map out a strategy for manpower planning so as to fulfill the demands of new business and minimize operation costs related to training apprentices and recruiting experienced workers. This paper first analyzes the demand and supply of workers for IT service in a knowledge-intensive field. It then presents optimal human resource planning via the familiar method of stochastic process - queueing analysis

The Bank of Canada's Business Outlook Survey: An Assessment

Since the autumn of 1997, the Bank of Canada's regional offices (located in Halifax, Montréal, Toronto, Calgary, and Vancouver) have conducted consultations with businesses across Canada on a quarterly basis. These consultations are now referred to as the Business Outlook Survey (BOS). The BOS provides a timely source of information on what businesses are experiencing and planning. Business consultations are timed to feed into the decision-making process that precedes the Bank's fixed dates for announcing monetary policy decisions. The consultations are structured around a questionnaire. Every quarter, 100 firms that reflect the diverse composition of the Canadian economy in terms of region, type of business activity, and firm size are interviewed. Because the BOS is a relatively new tool, the survey time series is short. The assessment presented in this paper, which is based on charts and correlations, is intended as an initial guide. The findings suggest that the survey serves as a barometer of the Canadian economy and provides leading signals of future activity. The interview responses also inform the Bank about production-capacity constraints, labour shortages, and inflation expectations.Business fluctuations and cycles; Domestic demand and components

Adjusting ICT Capacity Planning by Minimizing Cyber Crime Effects in Urban Area: A System Dynamics Approach

In ICT capacity planning process, many organizations or institutions ignore unconsciously other components except statistical data of bandwidth utilization of ICT products. On this occasion, the ICT capacity planning process is analyzed by using system dynamics that considers some factors or components which are combinations between technical and non technical aspects such as: business, education, ICT infrastructure, ICT usage and cyber crime. Simulation of interrelationship between the components is conducted to understand the behavior of the system. System dynamics gives us input on correction of the statistical data by minimizing cyber crime effects. In this paper, it is also introduced the System Breakdown Structure (SBS), a technique to breakdown a big and complex system into smaller and manageable components. The objective of this SBS is to make system dynamics more expandable in hierarchy way in analyzing a system

A semantic approach to monitoring business process performance

The productivity and profitability of organizations depend on the efficacy of their business processes. Monitoring the performance of these processes in delivering organizational value propositions provides a basis for critical managerial decision-making activities including work scheduling, capacity planning, and process design or refinement [8] . Business processes are automated in whole or in part using workflow management systems (WFMS), where documents, information, and activities flow between participants according to existing process models and rules [9]. Workflows are abstractions of business processes that are typically modeled as deterministic, action-event sequences in WFMS [8] . Organizations employ tactical WFMS with sampling-based schemes or data-driven operational WFMS using firsthand observations for process evaluation. Managing the performance and quality of business processes based on accurate performance measures has direct impact on the success of an organization [8, 10]

Business Process Re-engineering and Information Security Planning: Opportunities for integration

Business process re-engineering (BPR) has come to recognize a need for the adoption of socio-technical methodologies and capabilities for knowledge representation of qualitative concerns. Security planning and decision-making has a similar need, and furthermore socio-technical methods common to BPR can be usefully applied in this capacity. The introduction of security models like Defense-in- Depth and similar efforts to recognize the organizational impact of security planning in operational security management serve as an initial step in educating security personnel and provide a more comprehensive view, but unfortunately, security decision-making has traditionally relied almost solely upon quantitative risk assessment, cost/benefit mechanisms, and related, functionalistic methodologies. This greatly limits the representational capacity of the decision process, and with it the possible dimensions of analysis in which to consider security issues. Within this paper, we briefly examine security planning and the relevant techniques of BPR and Socio-technical design, and present a framework for their integration within the context of information security. It is our contention that such methodologies can be utilized in the security decision process to facilitate representation of subjective concerns and broadly-defined issues germane to security policy, within an organizational context

Estimating capacity and resource allocation in healthcare settings using business process modelling and simulation

Healthcare involves complex decision making from planning to resource management. Resources in hospitals are usually allocated by experienced managers,however, due to an inherent process complexity, decisions are surrounded by uncertainties, variabilities, and constraints. Information Systems must be robust enough to provide support to stakeholders, capable of controlling and support work flows. The present work explores the required synergy when combining business processes with discrete event simulation. The objective is to estimate performance indices and address capacity management of a surgical center as a case study.Postprin
