The importance of management innovation and consultant services on ERP implementation success
2011
Enterprise resource planning (ERP) implementation has been an important activity for improving efficiency. However, an ERP system is a critical investment that can significantly affect future performance of a company. Many ERP projects report an unusually high failure rate. This study empirically investigates the involvement of management consultants in ERP implementation success. The results from our field survey of 134 ERP end-users in Spanish ceramic tile companies show that ERP implementation success significantly depends on the quality of consultant services. The results also indicate the importance of internal management throughout the learning process. Overall, these findings contrib…
Supporting Small Medium Enterprises planning through the use of a step-by-step System Dynamics model building process
2011
This paper aims to support small medium enterprises (SMEs) in business planning through the use of system dynamics models. In particular, it has been hypothesized that through the use of a step-by-step system dynamics model building process SMEs’ entrepreneurs can better understand the net of cause-and-effect relationships underlying company financial and non-financial results. Such an approach also enables decision makers to improve their understanding about the figures portrayed in a balance sheet. In order to reach such a goal, this study has been carried out through the use of a case-study. The small company investigated is a leather handcraft operating in Indonesia. The paper makes e…
Dealing with Product Similarity in Conjoint Simulations
2001
One of the reasons conjoint analysis has been so popular as a management decision tool has been the availability of a choice simulator. These simulators often arrive in the form of a software or spreadsheet program accompanying the output of a conjoint study. These simulators enable managers to perform ‘what if’ questions about their market—estimating market shares under various assumptions about competition and their own offerings. As examples, simulators can predict the market share of a new offering; they can estimate the direct and cross elasticity of price changes within a market, or they can form the logical guide to strategic simulations that anticipate short- and long-term competiti…
The Swot Model and the Role of These Activities to the Training of the Future Specialists in Expertise and Quality Control of Milk and Dairy Products
2014
Abstract The present drafts regarding the quality of milk and dairy products, define it as a controlled act of creation with known accuracy that can be reached by applying constitutive control systems of the processing technologies that are present in all proceeding phases of the product. In order to achieve the purpose and to apply it in the production process by students – future specialist, we use as a teaching-learning technique the SWOT Analyze. The SWOT analysis is an efficient method that is used in the teaching technique, especially when planning the strategy in order to identify the potentials and the priorities.
El efecto del tipo de producto fabricado y del tamaño de la empresa en los resultados productivos de las empresas de pavimentos y revestimientos cerá…
2006
En este artículo, describimos los datos recogidos en las entrevistas realizadas a 101 directores de producción y en las visitas posteriores a sus plantas. En él, presentamos la importancia que tiene el tipo de producto fabricado y el número de trabajadores en plantilla, para explicar las diferencias que existen en los resultados productivos de las empresas. Algunos indicadores como el plazo de fabricación, la cantidad de inventario de producto terminado o la productividad por operario, son sensiblemente diferentes en las distintas agrupaciones de empresas. Sin embargo, la satisfacción percibida por el mando de producción apenas varía al agrupar las empresas por producto fabricado.
Possibilistic Programming and Gas for Aggregate Production Planning under Vague Information
1999
In production planning activities, aggregate planning is surely the phase where the lack of information is more relevant. The reasons for that can be summarised in: a) the planning product is an aggregate one, very often not corresponding to actual products; b) the delay from the actual production is relevant so that information regarding actual production resources availability and performances are vague; c) the planning activity is often based on forecasts. On the other hand, all the subsequent production planning activities are based on the result of aggregate planning. In the paper a research going on at the Workgroup for Soft Computing Application in Manufacturing is presented. A Decis…
Ergonomic Indicators and Physical Workload Risks in Food Production and Possibilities for Risk Prevention
2021
The food industry is the most important and largest manufacturing industry in Latvia, producing almost a third of all manufacturing output. Employees in a food production enterprises are exposed to a variety of ergonomic risks: monotonous work movements that can be repeated up to 1000 times a day, overloads that exceeds 30 kg in lifting and moving operations, forced working postures, fast work pace. The aim of the study was to identify ergonomic indicators related to physical load for packers in one medium-sized company producing potato starch in Latvia. When summarizing the results of the survey on burden-lifting rates, it should be noted that, in a shift, 30% of packers lift the burden fr…
Economic lot scheduling on multiple production lines with resource constraints
2003
Abstract This paper deals with the multiple production line economic lot scheduling problem, where some items cannot be produced concurrently since they compete for some discrete resources. In particular, cyclic schedules are sought for a problem where identical production lines are present, lost sales are allowed, and minimization of the long-range production, setup, inventory, and shortage penalty costs are required. A heuristic procedure for this problem is introduced, a numerical example is worked out and some computational experiments are presented.
Application and assessment of IDEF3‐process flow description capture method
1995
The IDEF techniques have been developed in projects sponsored by the US Air Force in order to describe, specify and model manufacturing systems in a structured graphical form. These techniques can be classified in two categories: the “modelling” and the “descriptive” varieties. Compares two IDEF methods (one of the modelling type and one of the descriptive type) in order to represent (model or describe) two different aspects of an industrial organization. The methods compared are IDEF0, function modelling method, and IDEF3, process flow description capture method. Concludes that when considering the sequencing of the activities in process, aiming at highlighting their eventual simultaneity,…
Performance analysis of the closed loop supply chain
2012
Purpose The question of resource scarcity and emerging pressure of environmental legislations has brought a new challenge for the manufacturing industry. On the one hand, there is a huge population that demands a large quantity of commodities; on the other hand, these demands have to be met by minimum resources and pollution. Resource conservative manufacturing (ResCoM) is a proposed holistic concept to manage these challenges. The successful implementation of this concept requires cross functional collaboration among relevant fields, and among them, closed loop supply chain is an essential domain. The paper aims to highlight some misconceptions concerning the closed loop supply chain, to d…
