Abstract null null Supply chains require the interaction between retailers and suppliers in a dynamic environment. One frequent and costly source of inefficiencies produced by these interactions is known as the bullwhip effect. The bullwhip effect takes place when the variability of orders increases as one moves up the supply chain. However, the impact of this variability is influenced by retailers who compete both for supply and demand. This study systematically explores the impact of the bullw...

Abstract null null The manufacturing industry is confronted with the growing demand of personalized products of small batch sizes. In other words, the producers are faced with the satisfaction of heterogeneous customer needs through individualization and the realization of scale effects along the value chain. This study is among the first that proposes a mixed-integer programming model to obtain the optimal configuration of a supply network comprising of a pool of suppliers to satisfy the demand...

Abstract null null Physical Internet (PI) is a new concept to ensure global mobility of physical objects. Conventionally, logistics networks are closed and independent. Under the concept of PI, they are transformed into an open logistics network, providing an efficient way to relocate physical goods to a given place in a short period of time. A hyperconnected city logistics system is conceptualized as the final segment of a PI-network. It uses regional and city hubs as the final leg of last-mile...

Abstract null null It is estimated that 12000 tons of plastic waste is annually generated from the agricultural sector in Finland, and more than half of it comprises bale wrap films. Up to 70% of plastic film waste from the agricultural sector in Finland goes into landfills, and only around 10% is recycled. Recycling plastic material is desirable in order to close the loop in achieving a circular economy. This paper aims to assess the environmental and economic implications of bale wrap collecti...

Abstract null null Many service systems in various type of industry operate under a policy according to which customers are not allowed to directly approach the senior server of the system. If the senior server's intervention in the service is required, the junior server who handles the request approaches the senior server on behalf of the customer. Thus, the service is divided into two phases, where the first phase (e.g., obtaining information or performing an initial service) is conducted by o...

Abstract null null The circular economy is gaining momentum in political and academic agendas. However, little is empirically known about circular economy supply network configurations, dynamics and coordination mechanisms. In aiming to fill this theoretical and practical gap, this study employs a multiple case study of seven circular supply networks from different industries using coding, within- and cross-case analysis. As the study's main theoretical contribution, an innovative framework is p...

Abstract null null We consider the case where a large-scale entry of ride-hailing vehicles have significant impacts on the taxi market, which may result in many taxi drivers being forced to withdraw from the transport industry or promote the development of the whole transport industry. Specifically, we examine how an on-demand ride-hailing platform in competition with the traditional taxi industry designs its pricing strategies under the unregulated and regulated pricing scenarios, and we focus ...

Abstract null null We develop a model of a firm with multistage investment options and a bank providing a commitment for financing using a credit line. We analyze differences in beliefs between equity holders and the bank about the risk of assets and show that unfavourable beliefs by the bank reduce credit line capacity and lead to underinvestment. Constraints on alternative sources of financing cause firms to heavily rely on bank credit lines even when facing unfavourable beliefs by the bank ab...

Abstract null null The impact of 3D printing, or additive manufacturing, on a supply chain, consisting of a manufacturer and retailer, that utilizes a wholesale-price contract and serves stochastic customer demand has been studied in this paper. 3D printing is an evolutionary manufacturing technology which is attracting many firms and governments. Its impact, however, on supply chains remains unexplored. A 3D printer can be purchased by either the manufacturer or, in a more novel situation, the ...

Product proliferation has been adopted to increase sales introducing variants that may lure new customers, thus expanding the companies' reference market and potentially increasing the overall profit. However, extending the product-portfolio may imply product cannibalisation, increased costs, unproductive variety, and value-destroying complexity. In this paper, we develop a newsvendor-based model to analyse profitability, sales revenue, costs, and market share considering product proliferation a...
