    Kebijakan inventory pada komponen darah merupakan suatu permasalahan yang kompleks dikarenakan adanya ketidakpastian supply dan demand. Ketidakpastian supply dan demand akan menyebabkan terjadinya shortage dan wastage pada komponen darah dikarenakan darah memiliki umur pakai yang terbatas, namun memiliki tingkat service level yang tinggi. Oleh karena itu, tujuan dilakukan penelitian ini adalah untuk mengetahui keputusan kebijakan inventory yang paling optimal agar dapat memenuhi service level yang diharapkan dengan mempertimbangkan shortage dan wastage. Objek penelitian ini adalah inventory pada komponen darah packed red cells, trombosit dan plasma di UTD PMI DKI Jakarta dengan menggunakan metode continuous riview system. Continuous riview system merupakan metode pengendalian tingkat persediaan secara terus menerus, tanpa memperhatikan interval waktu, sehingga posisi stok akan selalu diketahui. Hasil penelitian ini diperoleh keputusan alternatif service level dengan menggunakan matriks pay off yang digunakan pada masing-masing komponen sehingga diperoleh 95% untuk komponen packed red cells, 85% untuk komponen trombosit dan 85% untuk komponen plasma. Dari masing-masing service level tersebut dapat ditentukan safety stock dan reorder point dengan nilai expected payy off terbaik yang dapat digunakan sebagai acuan blood bank lab distribusi PMI DKI Jakarta untuk menentukan keputusan kebijakan inventory

    Programa de educación para la salud: promoción de la donación de sangre mediante aféresis

    Introducción: En la actualidad la donación de sangre continúa siendo el único método de obtención de los componentes sanguíneos para su posterior transfusión a pacientes; sin embargo, en los últimos años se ha estabilizado el número de donaciones. Mientras la demanda de sangre va en aumento, existe otra técnica más eficiente denominada aféresis, pero a pesar de ello, durante el 2016 sólo se obtuvieron así un 3% de las donaciones. Objetivo: Diseñar un Programa de Educación para la Salud desde Atención Primaria para formar a la población sobre la donación de sangre mediante aféresis. Metodología: Se ha realizado una búsqueda bibliográfica en bases de datos, páginas web de Bancos de Sangre y organismos oficiales. Conclusión: La mejor forma que tiene Enfermería para dar a conocer e incrementar la donación de sangre mediante aféresis es por medio de la elaboración de un Programa de Educación para la Salud. Palabras clave: “Aféresis”, “Donación de sangre”, “Donante de sangre”, “Enfermería”, “Transfusión sanguínea”, “Programa de Educación para la Salud”.<br /

    Modelling of the collections process in the blood supply chain: a literature review

    Get PDF
    Human blood is a scarce resource and its role in healthcare is fundamental, with donated blood saving the lives of many on a daily basis. The blood supply chain is responsible for the transfer of blood from donor to the recipient, but the availability of such an invaluable resource as human blood is ultimately attributable to the many voluntary donors. Thus, the efficiency of the collection of donated blood is crucial to the downstream effectiveness of the blood supply chain. We provide a detailed review on the use of quantitative methods for the process of blood collection from donors. We describe the functional areas which are appointment scheduling, collection policy, crisis situation, donor demographics, location/clinic planning, staff utilisation and vehicle routing. Furthermore, we analyse the existing literature with regards to methods, modelling objectives and the planning levels such as strategic, tactical and operational. Finally, we break down the articles into whether or not case studies lead to the implementation of the methods in practice. In total, we review 46 relevant publications on the intersection between OR/MS and other disciplines. We use our presented framework to categorise the existing approaches and highlight gaps such as scheduling of both staff and appointments for blood donation clinics

    Whole blood or apheresis donations? A multi-objective stochastic optimization approach

    No full text
    In the blood supply chain, several alternative technologies are available for collection and processing. These technologies differ in cost and efficiency: for example, collection by apheresis requires very expensive machines but the yield of blood products is considerably greater than whole blood collection. Blood centre managers are faced with the difficult strategic problem of choosing the best combination of technologies, as well as the equally difficult operational problem of assigning donors to collection methods. These decisions are complex since so many factors have to be taken into account, including stochastic demand, blood group compatibilities, donor availability, the proportions of blood types in both donor and recipient populations, fixed andvariable costs, and process efficiencies. The use of deterministic demand forecasts is rarely adequate and a robust decision must consider uncertainty and variability in demand as well as trade-offs between several potentially conflicting objectives. This paper presents a multi objective stochastic integer linear programming model to support such decisions. The model treats demand as stochastic and seeks to optimize two objectives: the total cost and the number of donors required. To solve this problem, we apply a novel combination of Sample Average Approximation and the Augmented Epsilon-Constraint algorithm. This approach is illustrated using real data from Bogota, Colombia

    This book provides the current status of research on the application of OR methods to solve emerging and relevant operations management problems. Each chapter is a selected contribution of the IO2021 - XXI Congress of APDIO, the Portuguese Association of Operational Research, held in Figueira da Foz from 7 to 8 November 2021. Under the theme of analytics for a better world, the book presents interesting results and applications of OR cutting-edge methods and techniques to various real-world problems. Of particular importance are works applying nonlinear, multi-objective optimization, hybrid heuristics, multicriteria decision analysis, data envelopment analysis, simulation, clustering techniques and decision support systems, in different areas such as supply chain management, production planning and scheduling, logistics, energy, telecommunications, finance and health. All chapters were carefully reviewed by the members of the scientific program committee.info:eu-repo/semantics/publishedVersio
