Abstract

Demonstrates the application of spreadsheets in simulating queuing systems with arrivals from a finite population. The problem is referred to as the machine repair problem where the members of the queue are machines that are breaking down and the servers are the technicians repairing the broken machines. The total number of machines are finite and pre‐specified. The technique for the development of the simulation is illustrated with six machines. Describes the approach for developing a generalized simulation model with any number of machines.

Abstract

A methodology of structuring a garment production simulation model using a spreadsheet is described to minimize the average daily production cost through the investigation of various man‐machine combinations. The capability and usability of an easily available modern spreadsheet Excel 7.0 to simulate a simple garment production system is accessed with an attempt to demonstrate the simulation model building in a user friendly environment rather than learning and using costly simulation programming languages or simulation software packages. Simulation has evaluated the resource utilization and measured the system performance and developed strategies for taking operational decisions in a logical and better way to minimize the garment production cost. It may also assist and benefit the garment production managers to plan, design and operate their systems in an efficient manner in a competitive environment.

Abstract

Spreadsheet software is now widely used as a decision‐making tool, owing to the simplicity and ease with which generalists can analyse and obtain fast and precise information. Through spreadsheet programs, a non‐specialist can conduct an exhaustive “what if” search in order to make decisions regarding “what if” questions. Now, with the availability of a random number function in most spreadsheet programs, simulation models can be carried out within the spreadsheet. How the waiting‐line problem can be simulated using a spreadsheet package is demonstrated. The simulation process serves as a decision‐support system to assist decision makers to determine the appropriate service level based on number of servers. Arrival of customers to obtain service is stochastic in nature and therefore can be assigned a probability distribution using historical data. Through the random‐number function, which is available in most spreadsheet programs, random numbers can be generated and used along with the assigned probability distribution to assist in making the service‐level decision.

Abstract

Reviews the literature on capacity planning at strategic, tactical and operational levels but points out that, in practice, many enterprise resource planning systems make unrealistic assumptions for production planning; and the advanced production software packages which can deal with uncertainty are both complex and expensive. Uses a theoretical company to demonstrate how a normal Excel spreadsheet can be used in conjunction with a common add‐on package (@RISK) to improve analysis and run Monte Carlo simulations as a basis for decision making. Compares the results produced with standard spreadsheet analysis and discusses the additional financial and operational insights they provide into the implications of different capacity levels under conditions of uncertainty. Warns that the validity of the simulation depends on the quality of the data and model; and that human judgement is still required to actually make a decision.

Abstract

Suggests that simulation of the workflow component of a computer supported co‐operative work (CSCW) system has the potential to reduce the costs of system implementation, while at the same time improving the quality of the delivered system. Demonstrates the value of being able to assess the frequency and volume of workflow transactions using a case study of CSCW software developed for estate agency co‐workers in which a model was produced based on a discrete‐event simulation approach with implementation on a spreadsheet platform.

Abstract

The application of just‐in‐time manufacturing techniques in batch chemical processing environments, under conditions of variable demand, imposes significant capacity management problems. Making decisions which involve levels of customer service and resource untilization can be aided by the application of the calculation methodology outlined, which uses standard spreadsheet techniques and forecast queue analysis. Presents a case example to clarify the links between service levels and resource utilization which can aid management decisions regarding timing, levels of stocks and sizing of facilities.

Abstract

Purpose

This paper aims to advance an integrative perspective of dynamic relationality in negotiation research by providing a symbiotic solution to modeling the cultural adaptation process in intercultural negotiations.

Design/methodology/approach

Based on a solution-oriented symbiotic approach, the authors analyze negotiators’ combination strategy to propose the dynamic convergence of dyadic relational negotiation behavior (RNB) both as a descriptive framework and a prescriptive solution to behavioral congruence in intercultural negotiations. The authors use spreadsheet platform with artificial data input to simulate various RNB dynamics between negotiators.

Findings

The authors identify the research gap between the arelational, static paradigm in negotiation literature and the relational, dynamic reality in negotiation practices, develop a fourfold typology of the existing negotiation research and propose the construct of RNB. The authors simulate the dyadic dynamics of RNB in a symbiotic framework. Results illustrate varied dyadic patterns of convergent RNB dynamics, demonstrating the effectiveness of the symbiotic solution to achieving behavioral congruence under multiple conditions. Propositions are then presented to predict negotiators’ initial relational behavior, describe dyadic coevolution of RNB in intercultural negotiations and explicate the relevant chronic consequences regarding relational and economic capital.

Originality/value

This paper fills a significant knowledge gap in the extant cross-cultural negotiation literature by addressing dynamic behavioral adaptation through a relational lens. This symbiotic framework is both descriptive in its predictive capacity to simulate the complexity of non-linear negotiation environment, and prescriptive in its directive capacity to guide negotiators’ plan of action given each other’s observed behavior with a probability estimation.

Abstract

An angel/venture capitalist could invest in an Internet sheet-music publishing start-up. The chance of success multiplied by the value, if successful, suggests that this isn't a good investment. Nevertheless, several friends suggest the optionality present in the venture: abort an unsuccessful website and sell the technology; switch the technology if the website is good, expand, buyout. Decision trees and Monte Carlo simulations are used to value these options, which make the opportunity look very attractive.

Abstract

Purpose

Considerable amount of purchases in business-to-business (B2B) markets make through the tendering process. As technology keeps driving B2B procurement, both the supplier/contractor and buyer firms have settled down in their respective roles in the electronic-tendering environment. Researchers have ignored the supplier-side e-tender-driven marketing process that might lead to substantively successful financial performance. The purpose of this study is to improve the performance of an e-tender-driven marketing process of an original equipment manufacturer (OEM) incorporating the stakeholder's inputs.

Design/methodology/approach

Discrete event simulation modelling (DESM) has been used as a methodology to model, analyse and improve the process with the involvement of stakeholders at every stage of the study. Different scenarios are analysed to identify the near-optimal scenario based on agreed-upon key performance indicators.

Findings

Scenario that incorporated man-power sharing and eliminating avoidable activities gives the near-optimal solution for implementation.

Research limitations/implications

This study highlights that better insights can be gained by adopting the process-oriented view of the marketing–operations interface. Embracing a stakeholder-based consultative approach gives research a more practical outlook and reduces the gap between theory and practice. Suggestions for further research are provided.

Practical implications

B2B organizations, where lines between marketing and operations are blurred, can improve their marketing processes by implementing operations research tools.

Originality/value

This study provides an attempt to improve the performance of a supplier-side e-tender-driven marketing process of an OEM using the DESM methodology incorporating stakeholder's inputs.
