Selection Criteria for Six Sigma Projects in Slovenian Manufacturing CompaniesResearches reveal that successful six sigma implementation is related to proper six sigma project prioritisation and selection. This research is limited to the selection of six sigma projects in some manufacturing companies in Slovenia. The purpose of this study is to identify what criteria are considered for prioritisation and selection of six sigma projects and how six sigma projects are selected. A research sample is limited by the number of companies which have implemented six sigma so far. The results indicate that Slovenian manufacturing organisations tend to select six sigma projects based on criteria such as customer satisfaction, connection with a business strategy financial benefits, and growth of the organisation. Several tools and techniques such as quality cost analysis, brainstorming and interviews are used to identify and prioritise projects. Identification of the most commonly used criteria to select six sigma projects can help practitioners to select projects based on multiple criteria by using tools and techniques identified in this study. This topic has not been applied in the field of Slovenian manufacturing companies and thus it presents the first study in this field in Slovenia.

Control Limits

Sigma (σ) is a Greek letter that has become the statistical symbol and metric of process variation. Six sigma is a disciplined, customers focused process designed to help organizations to move towards the creation of near perfect products and services. Six sigma (6σ) increases quality by reducing variation, defects and costs. 6σ is used in almost all fields of human activity. 6σ has been considered a powerful business strategy that employs a well structured continuous improvement methodology to reduce process variability and drive out waste within the business processes using effective application of statistical tools and techniques. This article i) gives the general introduction about the concept of six sigma, ii) briefs about the two 6σ methodologies DMAIC and DMADV, which are most commonly used by the organizations to achieve 6σ performance level, iii) discusses some of the applications of these limits in reducing the process variability. Some remarks about the results of applications of 6σ, the future requirements and benefits of 6σ are also discussed.

Raw materials is a major requirement in the production process for manufacturing companies. in fulfilling the needs of raw materials for the production process, most manufacturing firms depends on suppliers. Supplier selection is an important part of manufacturing companies. From several supplier selection criteria, quality is one of the important criteria and it used in supplier assessment. Selecting suppliers based on the quality of their products will have a positive impact on manufacturing companies, such as increased profits through reduced operational costs and increased market share. In this study will compare two suppliers at manufacturing companies and choose one that has a higher capability value. The selection of suppliers is made using the yield index of Spk with a single characteristic. Supplier will be selected by comparing the yield ratio of two suppliers. Numerical calculations are performed on suppliers based on pH levels on the leather. The pH level on the leather will affect the color. A low pH may result color degradation earlier, whereas a high pH may result poor color matching.

The picking process in warehouses is an important step in global supply chains because it causes significant costs and has a high impact on customer satisfaction. Especially manual systems may cause high costs and can generate many picking errors such as type and quantity failures. Using the example of consignment at an international manufacturer located in Switzerland, this contribution provides in-depth fundamentals on picking processes. The picking system, typical workflows of manual picking procedures and theoretical considerations of optimal picking quality are given. Using a quality cost as well as a process cost analysis and a cause and effect analysis, the picking process is investigated in this scenario. It turns out that the optimal picking quality is surpassed in the case, which requires a systematic process re-design in order to cut costs. Therefore exemplary technical, organizational and soft best practices are shortly presented. In the scenario a business and technical case of the introduction an innovative weighting system is described.

This chapter studies Critical Success Tools and Techniques (T&Ts) of Six Sigma (SS) strategy reported by researchers and practitioners. The main objectives of this research are to describe the current situation of SS and collaborate in the understanding of its successful implementation. This study was carried out through an extended literature review. Moreover, two periods of time were analyzed in order to emphasize on the evolution of SS. Such analysis relied on odds-ratio and hypothesis testing for proportions to study the most important T&Ts reported in almost two hundred of successful works related to SS projects. Afterwards, such T&Ts were identified and described. From this perspective, this chapter can be a useful guideline for training in companies, since it highlights the T&Ts most frequently used in successful projects, which have managed to improve the processes, reduce costs, and increase customer satisfaction in companies.

Six Sigma and Lean Manufacturing are the two most popular and successful programs espoused by the industries over the last few decades. Many companies such as Toyota, Danaher Corporation, General Electric, Motorola and many others have achieved impressive results by implementing either a Lean or Six Sigma methodology in their organisation. Six Sigma, originated in Motorola in mid 1980s, brought revolution in the industries worldwide and has become the long term business strategy to achieve competitive advantage and to excel in operations excellence. Six Sigma is widely recognized as a methodology that employs statistical and non-statistical tools and techniques to maximize an organization’s Return on Investment (ROI) through the elimination of defects in processes (Antony et al. 2011). Lean Manufacturing, on the other hand, was another quality initiative proposed by Americans in response to compete with Japanese manufacturers and its superior manufacturing techniques (following the concept of Toyota Production System (TPS) to resolve quality problems in their organization) as their import became serious concern to western producers.

Modelling Task

A comparative study of several recently proposed one-dimensional sedimentation models has been made. This has been achieved by fitting these models to steady-state and dynamic concentration profiles obtained in a down-scaled secondary decanter. The models were evaluated with several a posteriori model selection criteria. Since the purpose of the modelling task is to do on-line simulations, the calculation time was used as one of the selection criteria. Finally, the practical identifiability of the models for the available data sets was also investigated. It could be concluded that the model of Takács et al. (1991) gave the most reliable results.
