Lean Information Management in Industrial Context: an Experience Based on a Practical Case (pp. 107-114)

Sofia Soares, Leonor Teixeira
The interest in the application of the Lean methodology to the administrative processes has been abruptly catching the attention of multiple managers. The need to reduce (direct or indirect) costs through the processes’ improvement, not only productively but also administratively, is gaining even more weight for organizations. Thus, there are many companies which are starting to reflect on their processes and on a way of becoming more competitive and more efficient. Through the improvement of the management information mechanisms, it is possible to make processes more efficient so that they can release resources for other activities. This is the context in which this project emerges, which aims to improve a Logistics process (customer service), using a simple, objective and functional solution with an immediate response to the elimination of waste in a decision making process. Behind this implementation, there is a whole study based on Lean methodologies that help to understand the project, to identify the improvements and to structure its conception.

An AHP-MOLP Approach on Prioritizing Competitive Strategies Toward Sustainable Business (pp. 95-106)

Lanndon A. Ocampo, Eppie E. Clark
Incorporating sustainability in business processes has extended its scope from a supply chain or life cycle perspectives to highly, technical engineering designs of products and processes. Streamlining of opportunities for possible integration of sustainability and business process has shown an overwhelming increase of research interests in current literature. At the conceptual level, decision-making on areas that concern strategy or long term goals is a crucial task as it directs future status of the firm, at least in the area of sustainability. Thus, long term decisions must be critically designed to address future conditions of the firm. This paper explores how competitive dimensions influence the triple-bottom line. A hybrid approach using analytic hierarchy process (AHP) and multi-objective linear programming (MOLP) is shown in this paper to provide insights on such influences. A case study of a group of experts is shown in this work. Results show that businesses which maintain quality as their competitive advantage are likely sustainable as it impacts both economic and social performances. It is also shown that economic and social performances can be traded-off to increase environmental performance. The significance of this paper lies in presenting a range of alternative Pareto optimal solutions which are relevant in providing decision-makers a trade-off in sustainable business performance.

A Visual Board to Facilitate Production Flow Regulation at Sequential Processes (pp. 85-94)

Goh Wen Jiun, Chin Jeng Feng, Shahrul bin Kamaruddin, Nur Amalina binti Muhammad
A visual system allows one to assess the production status of a shop floor at a single glance and detect abnormalities like deviations from the production plan. This paper presents a case study of a visual system application on an electronics backend assembly that consists of several mixed-model sequential processes. The production flow is regulated by a push system. Isolated scheduling at the front end significantly contributes to erratic arrival of parts at the backend. A generic visual board was designed and implemented to avoid significant inventory build-up, shorten average flow time, and ensure maximum production leveling. The visual board is named as visual Work-in-progress (WIP) flow monitoring board and is described in terms of its physical appearance, component functions, and operating procedures performed by different levels of staff. The paper also includes the implementation of the visual board and performance evaluation after ten months of execution. The system was found to produce positive results.

Priority Analysis on the Reliability Parameters of an Existing Model (pp. 77-84)

Seyed Hossein Khodaei, Masoud Rahiminezhad Galankashi, Adnan Hassan
The basic goal of this paper is to create an alternative based analysis in a reliability model. Despite the vast amount of studies on reliability analysis and related techniques, the evaluation of the importance of different alternatives is less investigated. In order to fill this gap, this research was carried out to systematically investigate the result of setting three different scenarios on a reliability model. A model of reliability system was proposed based on redundancy allocation problems. There are certain limitations (Weight and Cost)of proposed model. In particular, three different scenarios (the results of Failure Rate preference, Weight preference and Cost Preference) was presented. This investigation operated based on the assumption of allocating only one redundant component for the subsystems, and the main goal of this investigation is to determine what would be the results when lowest possible Weight, lowest possible Cost and lowest possible failure rate is needed.

Financial and Human Benefits of Lean Production in the Plastic Injection Industry: an Action Research Study (pp. 61-75)

Vitor Resende, Anabela C. Alves, Alexandre Batista, Angela Silva
This paper presents the results of a Lean Production project implementation developed in a plastic injection company. The main aim of the project was the application of Lean principles and tools involving the stakeholders of the company. The first tool applied was the VSM to diagnose the production system and to identify the wastes and the main issues for improvement. Some proposals were presented and implemented using Lean tools such as 5S, PDCA cycle, Kanban, SMED and Kaizen. Some tangible and financial results obtained were an increase of productivity of the assembly lines by 12%, of the operating income by 6%, a reduction of the cycle time of six dies to 10% and a reduction by 15% of tool changeover time and an increase of total incomes estimated in €360,000.00. Intangible results were the operators’ engagement and involvement with the continuous improvement and with Lean implementation.
