Original scientific paperIn an underdeveloped remanufacturing system, poor infrastructure and low technical level impede further development of remanufacturing. To overcome this obstacle, a huge amount of fixed investment is required to improve the remanufacturing system. However, this investment inevitably influences the manufacturer's manufacturing/remanufacturing decision-making economically. The relationship between fixed investment and recycling ratio was investigated, and the two-and multi-period manufacturing/remanufacturing mixed optimization models were developed. Based on the Karush-KuhnTucker (KKT) conditions, the optimal manufacturing/remanufacturing and fixed investment policies were obtained in closed-form expressions. Moreover, the influences of the fixed investment were analysed. Results show that the optimal policies are significantly influenced by the degree of underdevelopment of the remanufacturing system. When the remanufacturing system is underdeveloped, the manufacturer shows a lack of enthusiasm in remanufacturing, thereby resulting in the decrease of the investment and the recycling ratio. The manufacturer raises the sale price to alleviate the loss caused by fixed investment, but the total manufacturing quantity and profit decrease. In the multi-period case, the manufacturer gradually increases the investment for continuously improving the remanufacturing system to increase the recycling ratio and obtain additional profits from remanufacturing. The proposed models can effectively provide the reference for determining the reasonable manufacturing/remanufacturing and fixed investment policies in the underdeveloped remanufacturing system.

Za otklanjanje ove prepreke i unapređenje sustava preradbe potrebna su velika fiksna ulaganja. Ta ulaganja nedvojbeno utječu na proizvođača i ekonomičnost u donošenju odluke o proizvodnji /preradbi. Analizirao se odnos između omjera fiksnog ulaganja i preradbe te su razvijeni modeli optimizacije s dva i više perioda proizvodnje/preradbe. Na temelju Karush-Kuhn-Tucker (KKT) uvjeta, dobivene su smjernice za optimalnu proizvodnju/preradbu i fiksno ulaganje. Uz to, analizirani su učinci fiksnog ulaganja. Rezultati pokazuju da na optimalne odluke značajno utječe stupanj nerazvijenosti sustava preradbe. Kad je sustav preradbe nedovoljno razvijen, proizvođač pokazuje manjak entuzijazma za prerađivanje, a to dovodi do smanjenja ulaganja i omjera preradbe. Proizvođač podiže prodajnu cijenu kako bi ublažio gubitak izazvan fiksnim ulaganjem, ali ukupna proizvodnja i profit opadaju. U slučaju multi-perioda, proizvođač postepeno povećava ulaganje u trajno poboljšanje sustava preradbe kako bi se povećao omjer recikliranja i dobila dodatna z...

“…From social concerns about 3R (Reduce-ReuseRecycle) activity worldwide, it is urgently-needed to construct a new supply chain management which incorporates reverse chains/logistics into traditional forward chains/logistics (Guide and Wassenhove, 2009;Jayant et al, 2012;Souza, 2013;Govindan et al, 2014;Stindt and Sahamie, 2014;Schenkel et al, 2015;Radhi andZhang, 2016, Cannella et al, 2016). The traditional forward chains/logistics consist of the flows from procurement of new materials through production of new products to selling them.…”

“…The reverse chains/logistics are composed of the flows from collection of used products through recycling parts from the used products to reuse the recycled parts. Also, a supply chain which organizes the forward chains and the reverse chains has been called a closed-loop supply chain, a reverse supply chain, or a green supply chain (GSC) (Guide and Wassenhove, 2009;Souza, 2013;Govindan et al, 2014;Stindt and Sahamie, 2014;Bhattacharya and Kaur, 2015;Gurtu et al, 2015). A supply chain which is considered in this paper is called GSC in terms of greening effort/initiatives (Swami and Shah, 2013;Ghosh and Shah, 2015) in promoting collection activity of used products and remanufacturing activity.…”

“…For the above topics, many previous studies regarding a GSC determined the optimal operations in the GSC so as to maximize the expected profit or minimize the expected cost under the uncertainties (Schenkel et al, 2015). There are some overviews of above topics (Fleischmann et al, 1997;Guide and Wassenhove, 2009;Souza, 2013;Govindan et al, 2013;Stindt and Sahamie, 2014;Bazan et al, 2016: Thiripura Sundari andVijayalakshmi, 2016). However, only considering the expectation for decision-making is insufficient because it ignores the risk attitude of the decision makers (Choi et al, 2008a;Chiu and Choi, 2016).…”

It is urgently-needed to construct a green supply chain (GSC) from collection of used products through recycling of them to sales of products using the recycled parts. Besides, it is necessary to consider the uncertainty in product demand as a risk in a GSC. This study proposes the optimal operations for a GSC with a retailer and a manufacturer. A retailer pays an incentive for collection of used products from customers and sells a single type of products in a market. A manufacturer produces the products ordered by the retailer, using recyclable parts with acceptable quality and compensates the collection cost of used products as to the recycled parts. This paper discusses the following risk attitudes: risk-neutral attitude, risk-averse attitude, and risk-prone attitude. Using mean-variance analysis, the optimal decisions for product order quantity, collection incentive, and lower limit of quality level, in the decentralized GSC (DGSC) and the integrated GSC (IGSC) are made. DGSC optimizes the utility function of each member. IGSC does that of the whole system. The analysis numerically investigates how (i) risk attitude and (ii) quality of recyclable parts affect the optimal operations. Supply chain coordination between GSC members to shift IGSC from DGSC is discussed.

ResumenEste artículo presenta los resultados finales de una investigación adelantada en el distrito de riego Usochicamocha del Departamento de Boyacá -Colombia, el cual enfrenta un problema a causa de la no devolución y recolección de la totalidad de los envases y empaques vacíos de plaguicidas que generan los agricultores. Debido a lo anterior, con la investigación se propone una configuración y funcionamiento de la red de logística inversa (LI) para la recolección, acopio y disposición final de los residuos de plaguicidas en dicha zona, para lo cual se desarrolla un modelo de programación lineal entera mixta con el fin de definir tanto las cantidades a recolectar y transportar a disposición final y evaluar la posibilidad de abrir nuevos centros de acopio. Los resultados del modelo matemático evidencian que, en promedio, se recolectan en cada finca 5 kg de residuos y que se envían 1106.58 kg a eliminación segura y 1292.31 kg a reciclaje.Palabras clave: Logística inversa; programación lineal; plaguicidas; retorno de envases ; disposición segura de envases; reciclaje 1 Universidad de Boyacá, jdsilva@uniboyaca.edu.co, http://orcid.org/0000-0001-7497-8632, Tunja, Colombia.
