We provide a continuation of the existing Activity Table Modeling methodology with a modular spreadsheets simulation. The simulation model developed is comprised of 28 modeling elements for the abdominal surgery cycle process. The simulation of a two-week patient flow in an abdominal clinic with 75 beds demonstrates the applicability of the methodology. The(More)
The simplex algorithm requires artificial variables for solving linear programs, which lack primal feasibility at the origin point. We present a new general-purpose solution algorithm, called Push-and-Pull, which obviates the use of artificial variables. The algorithm consists of preliminaries for setting up the initialization followed by two main phases.(More)
This paper examines whether Macedonian SMEs plan for the implementation of ERP projects and studies the effect of project planning practices on project success. Four project planning measures were taken into consideration: business case development, scope planning, baseline plan development and risk planning along with three measures of project success;(More)
The purpose of this work was to study the possibility of connecting two effective techniques (activity table and simulation) for carrying out business process modeling and improvement. The activity table is a technique for process modeling and improvement. Business process modeling is done by identifying the business processes and is continued by choosing a(More)
This paper discusses the problem of process model-ling and aims to introduce a process-oriented technique called the activity table to find a better solution for the problem mentioned. This is a simple and effective tech-nique, which is based on developing the activity table. Business process modelling is done by identifying the business processes and is(More)
Any enterprise consists of a number of business processes. Business process is a horizontal process that links different work processes in one or more functional areas of the organization to deliver the output of the enterprise. A work process consists of a set of activities that are performed to produce a certain output of the process discussed. This paper(More)
