“…The cost of availability of spare parts is a major success factor in maximizing aircraft utilization and lateral transshipments are a way of exploiting economies of scale in this environment (Kilpi and Vepsäläinen, 2004). The airline industry represents only a small proportion of the spare and service parts industry, where horizontal collaboration and inventory pooling is widely implemented (Satir et al, 2012, Kranenburg and van Houtum, 2009, Wong et al, 2007 .…”

Purpose: Are lateral transshipments an effective instrument to ensure the safe and efficient supply of blood? This paper will use the lens of institutional theory to determine how the blood supply chain can benefit from lateral transshipments and what requirements are necessary for their implementation. Design/methodology/approach: The research design comprises two stages. Firstly, 16 case studies clustered into 2 case groups were conducted with transfusion laboratories in UK hospitals resulting in the derivation of 8 key themes which were tested using a follow up survey. Findings: The blood supply chain acts under the influence of significant institutional pressures. Coercive pressures result from regulations enforced to ensure the safe supply of blood, normative pressures are imposed by society, demanding wastage is minimized and mimetic pressure from other hospitals fosters efficient supply chain operation. Lateral transshipments offer a powerful organizational tool to allow the blood supply chain to conform to these pressures. Research limitations/implications: This paper offers a novel institutional perspective on a complex supply chain issue where additional external pressures are seen to complicate the context. Due to the special characteristics of the blood supply chain, generalization of the findings to other industries must be done with care. Practical implications (if applicable): The paper confirms the benefits of lateral transshipments in a perishable product context. Special requirements for the blood supply chain / health care services are identified. Originality/value: The key contributions of this paper are five propositions which offer an institutional theory perspective on the application of lateral transshipment relationships in the blood supply chain.

“…The majority of the existing literatures on lateral transshipments have hitherto focused on deriving optimal or suboptimal transshipment policies as well as replenishment decisions under specific assumptions [6,[12][13][14][15]. The methods in the literature can be mainly grouped into four classes: mathematical programming [7,12,16], game theory, queuing theory [17], and simulation experiments [18].…”

Dynamic Complexities in a Supply Chain System with Lateral Transshipments

The horizontal interaction between retailers, coupled with replenishment rules and time delays, makes the dynamics in supply chain systems highly complicated. This paper aims to explore the impacts of lateral transshipments on the stability, bullwhip effect, and other performance measurements in the context of a two-tiered supply chain system composed of one supplier and two retailers. In particular, we developed a unified discrete-time state space model to address two different scenarios of placing orders. Analytical stability results are derived, through which we found that inappropriate lateral transshipment policies readily destabilize the supply chain system. Moreover, the lead time of lateral transshipments further complicates the stability problem. Theoretical results are validated through simulation experiments and the influences of system parameters on performance measures are investigated numerically. Numerical simulations show that lateral transshipments help improve the customer service level for both retailers. It is also interesting to observe that the demand of the two retailers can be satisfied even if only one retailer places orders from the upstream supplier.
