APLIKASI SIX SIGMA PADA PRODUK CLEAR FILE DI PERUSAHAAN STATIONARY

High quality of service is imperative for competitiveness of a service industry. In order to provide much better service, a deeper research on quality service is a necessity. One interesting and challenging aspect in researchin service quality is about measuring service quality. While some methods is proposed for measuring service quality, but every one of them did not offer satisfactory explanation in complex problems of measuring service quality, which is the vagueness and incompleteness in transforming linguistic explanation and scale of one’s opinion into numerical scale. One interesting method that incorporate the complexity and vagueness of linguistic explanation and scale into consideration is Qualitometro II method. This method will handle information expressed on linguistic scales without any artificial numeric scalarization and measure and control the quality of service. An interesting study of implementation of Qualitometro II in general medical clinic is conducted to examine the operation and impact of the Qualitometro II method with the assistance of a qualitometro software to ease the complex calculation algorithm. Result of the implementation is presented and evaluated for further study.

Developing electronic mango traceability in Indonesia

ABSTRACT Agricultural production in developing countries needs to meet global traceability requirements to enable food product export. A single case study of a multi-tier supply network provides a detailed description on features of developing traceability of mangoes harvested in Indonesia. This effort involves the integrated, time-limited effort of different professional actors in a project-based network. Developing food product traceability is a boundary-spanning effort; a need to coordinate both actors and the traceability project as an organisational entity. Organising food product traceability importantly involves integration of the different supply network actors as well as the time-limited integration of external actors with technical competence about the traceability system. The case reveals that these technical professionals in addition to organising the project also are decisive in creating an integrated supply network to facilitate the traceability development and system implementation. Findings indicate that developing traceability in developing economies is not much different today than developing this ability in economies commonly labelled as more developed.

Using DEMATEL approach to develop relationships of performance indicators on sustainable service only supply chain performance measurement

Service only supply chain (SOSC) concept is service supply chain (SSC) implementation on pure services. The globalization and stakeholder pressure makes operation of SSC should give the attention to the environment effect, community, economic and intangibility assets. SOSC performance measurement (SOSCPM) may be developed for measuring of performance for sustainability aspects and intangibility assets to meet customer satisfaction. This article discusses sustainable SOSCPM based on balanced scorecard (BSC), include sustainability aspects, intangibility and relations between perspectives and indicators. From literature review, it is found 34 performance indicators that must be confirm to expert and SC actors by survey. From survey validation using weighted average and level of consensus, it is found 29 valid indicators for processed by DEMATEL. From DEMATEL, it is found 26 indicators can be used on sustainable SOSCPM. Furthermore, innovation and growth perspective most influence to other, and customer perspective most important. Intangibility indicators incorporated on innovation and growth perspective very related with human resources. Finally, relations between perspectives and indicator used to design of BSC strategy maps.

Modified allocation capacitated planning model in blood supply chain management

Blood supply chain management (BSCM) is a complex process management that involves many cooperating stakeholders. BSCM involves four echelon processes, which are blood collection or procurement, production, inventory, and distribution. This research develops an optimization model of blood distribution planning. The efficiency of decentralization and centralization policies in a blood distribution chain are compared, by optimizing the amount of blood delivered from a blood center to a blood bank. This model is developed based on allocation problem of capacitated planning model. At the first stage, the capacity and the cost of transportation are considered to create an initial capacitated planning model. Then, the inventory holding and shortage costs are added to the model. These additional parameters of inventory costs lead the model to be more realistic and accurate.

The sustainability and performance measurement on supply chain in services industry: A literature review

The services industry growth has been significant relation with economic growth. A new paradigm is needed for services sector development. The supply chain and performance measurement able to sustain of services industry growth. The supply chain implementation in the services industry called service supply chain (SSC).The globalization and stakeholder pressure makes operation of SSC should more attention to sustainability issue which consists of economic, social and environment simultaneously on SSC. Furthermore, services industry can develop by implementation of the sustainable SSC and its performance measurement. The sustainable SSC implementation can minimize of negative operation effect to environment and social, and maximize of profit.Sustainable service supply chain performance measurements (SSSCPM) are still less explored. The purpose of this paper is to review the literature in the field SSC, SSSC, SSC performance measurement (SSCPM) and SSSCPM for identification of the SSSCPM frameworks and indicators. Beside, the result of review able to look opportunities for develop a new framework for SSSCPM at the operational level, tactical and strategic, multiplayer and close loop, the effectiveness of the integration and development of modeling and simulation for evaluation in the future.The services industry growth has been significant relation with economic growth.

The robust corrective action priority-an improved approach for selecting competing corrective actions in FMEA based on principle of robust design

In spite of being integral part in risk – based quality improvement effort, studies improving quality of selection of corrective action priority using FMEA technique are still limited in literature. If any, none is considering robustness and risk in selecting competing improvement initiatives. This study proposed a theoretical model to select risk – based competing corrective action by considering robustness and risk of competing corrective actions. We incorporated the principle of robust design in counting the preference score among corrective action candidates. Along with considering cost and benefit of competing corrective actions, we also incorporate the risk and robustness of corrective actions. An example is provided to represent the applicability of the proposed model.

A maintenance waste risk appraisal model based on modified failure mode and effect analysis (FMEA)

Establishment of an improved model for assessing criticality of waste in maintenance operation strongly supports the creation of sustainable manufacturing. However, contribution of previous maintenance engineering studies to above issue is very limited. If any, it is very few intended to create a model for ranking criticality of maintenance waste using risk management tool. In spite of the fact that utilization of risk appraisal tool has been introduced in earlier studies by modifying FMEA, some limitations are still existing and demanding for a better refinement. In this paper, an improved model for calculating the risk of maintenance waste using modification of FMEA is proposed. In evaluating risk criticality of maintenance waste, a new waste priority measure is presented via combining new additional dimensions extended from previous waste criticality evaluation models. In the new model, additional indices, the preventability and controllability scale of waste are included in an attempt to narrowing down limitations on using the detection indices only. An example on using the new waste reprioritization model for maintenance waste risk is provided. The proposed model offers an alternative perspective on evaluating the risk of maintenance waste and an improved model for maintenance waste alleviation.

Feeder bus routing problem using a genetic algorithm: Surotram case study

The feeder bus is needed to support the dedicated infrastructures (i.e. monorail and tram) in order to pick-up passengers from the bus stops in all location to the monorail/tram stations and vice versa. Planning of feeder bus routing is important to be conducted in order to determine the best flow of routes in each of monorail/tram stations. This paper proposes a Genetic Algorithm based approach to develop feeder bus routing model in order to determine the best flow of routes and minimum amount of feeder bus. Surotram project in Surabaya Mass Rapid Transit (SMART) project is selected as the case study in this paper. The results indicated that the base solutions of 12 feeder bus routes were wounded with 45 feeder-bus to serve 51 bus stops in all locations.
