    Full text link
    In this paper we will develop a spreadsheet-based Decision Support System (DSS) to determine the number of rattan depot and supply allocation to meet the production centers demand with case study in Solo Raya. The DSS incorporates database, model base, analysis tool, and Graphical User Interface (GUI) and user. Databases for storing data, the model base to keep models, analysis tool is required for solving the model and GUI allows users to interact with the database, model base and analysis tool. Data base, the base model and analysis tool are developed using the spreadsheet. The basic idea of the proposed approach is the spreadsheets can be used to build data-driven, model-driven DSS and solver-driven DSS. The model was developed by consider two stages of distribution network, multi commodities of raw rattan, and multi-periods of production plan. The DSS development approaches used in order to government can efficiently make the policy. DSS software interface is designed so user-friendly with point and click application so that users can operate quickly and easily. Users do not need to formulate a mathematical model despite they want to change index values or parameters repeatedly. The test results of case examples provided also give good results, where the software is capable for processing data based on selected model. The DSS is capable for providing location results and the allocation of raw or processed rattan at the depot on minimal total supply chain cost. The result may be a consideration for the policy makers to determine the right location of rattan depot. Keywords: decision support system, spreadsheet, location-allocation model, rattan industr

    A Facility Location-Allocation Model for Determining Number of Depot to Distribute Material in the Rattan Furniture Industry by Considering Dynamic Demand

    This paper is a study of a facility location-allocation problem in the rattan furniture industry. There are six production centers (PCs) of rattan furniture in Surakarta and its surroundings. However, their export sales are decline due to some possible problems in raw rattan distribution network from the sources centers (SCs), e.g. Borneo and Celebes Island to production centers. In the previous research, the model was expanded to support local government decide to determine optimal number of depot by consider static demand. This policy is aimed to cut the distribution channel and reduce total supply chain costs. Due to changing of global market, the demand is fluctuate. The previous model cannot anticipate this situation; consequently the local government needs a facility location-allocation model by considering dynamic demand. The objective of this research is to develop a model for supporting the local government to decide optimal number of depot by considers dynamic demand. A mixed integer non-linear programming (MINLP) was proposed to minimize total supply chain costs. The proposed model assumed that the demand for multiple products is known in advance. The potential raw rattan depot and source locations as well as their maximum capacities are also known. Finally, the proposed model can be used as instrument decision making to determine facility location-allocation. Keywords: dynamic demand, a facility location-allocation model, rattan industry competitiveness, total supply chain costs

    Designing Information System To Support Business Process Improvement In A Small-Mid Size Bottled Drinking Water Industry

    Due to inefficiencies of the business processes in small-mid size of bottled drinking water industries, it is necessary to improve them. The improvements are carried out in business processes of production, warehouse, delivery, marketing, and finance departments. The main causes of the inefficiencies are the inefficiencies of the business process itself and that the business processes of those departments were not integrated. This paper is concerned with designing information system to support for the integration of those departments. First, we mapped the business process of each department using flow diagram. Then analyze the inefficiencies of each department. Next, we redesign the business processes and standardize them. The next step is integrating the business processes by designing the information system. We design the information system modular. The modules are marketing module, production module, logistic module and finance module. Data Flow Diagram (DFD) is used to model the system. Relational database management system (RDBMS) is used to design the database. User interfaces are built to ease in using the program application. The outputs of the information system are reports and documents in monitor screen view and in printing. The validation showed that the information system designed can support the business process improvements. Keywords: business process improvement, integration, information system, small-mid size of bottled drinking water industr

    Collaborative supply chain is a specific topic in supply chain management and studied by industrial engineering students in supply chain management course. Unfortunately, conventional learning media cannot explain the phenomenon of collaborative supply chain to the students. This study aimed to design a dynamic learning media so that inter-company collaboration and information sharing on the activities of Supply Chain entities can be explained effectively to the students. The problem was solved using 3 (three) steps. First, the distribution network was described using mock up. It consists of miniature trucks, miniature network and miniature of the manufacturer-distributor-retailer embedded with tag and reader of RFID. Second, the Enterprise Resources Planning application was developed for supporting business activities. Third, we developed the integrator consists of monitor’s user interface and practice modules. The result of the research - an SCM-Simulator – will be able to improve learning skills of industrial engineering graduates, especially abilities to identify, formulate, and solve the activities of tactical plan & operational routines of Supply Chain entities. However, distribution module designed is for limited scale laboratory study of simple objects.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Penjadwalan Pekerjaan pada No-Wait Flowshop dengan Kriteria Minimasi Total Waktu Tinggal Aktual Menggunakan Algoritma Genetik

    Full text link
    This research uses genetic algorithm for no-wait flowshop scheduling problem. The shop requires the condition that each job be processed without any interruptions on all m machines and between two consecutive machine. This means that the start of processing a job on a given machine may be delayed in order to make the completion of the job on the machine coincide with this beginning of processing the job on the subsequent machine. The objective for the model is to minimize total actual flow time accommodating the condition that job to be processed arrive at the shop at any times when needed and the condition that the completed job be delivered at a common due-date. Genetic algorithm is randomly and structured search to find optimal solution. Numerical experience shows that for a given scheduling problem, genetic algorithm solution better than before (Yuniaristanto, 2001). Keywords : actual flowtime, genetic algorithm, no-wait flowsho

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
