Omni-channel retailing changes the distribution structures of retail companies. Integrating existing facilities, resources and processes may hold advantages regarding customer satisfaction and shopping convenience, as well as logistical efficiency, but are complex in the implementation. Since the logistical requirements for the packaging system in stationary and distance channels are different due to varying shipment structures, this hinders seamless channel integration. This paper investigates the role of the packaging system in omni-channel fashion distribution and identifies the respective challenges retailers and associated supply chain partners face regarding packaging when integrating sales and logistics channels. By means of a qualitative research approach including nine interviews from field experts, the current practices of retailers, packaging manufacturers and logistics service providers regarding packaging in OmniChannel retail are derived. The results indicate that the requirements towards packaging in the different channels, especially in integrated DC structures, interfere with a seamless channel integration. With regard to the role of stores in omni-channel retailing, channel-adequate packaging types need to be used for store pick-ups, and related process-changes are necessary for heightening efficiency. Packaging represents a restriction for distance shipments, fulfilled by stores. Primary packaging is an opportunity to support channel integration. However, this requires early and cross-company collaboration. The main theoretical contribution of this paper lies in identifying packaging related challenges preventing seamless channel integration into omni-channel distribution, stating initial packaging solutions to overcome those and providing an outlook towards future requirements for packaging in an omni-channel world. The paper has also strong managerial implications for retailing companies implementing integrated omni-channel structures, processes and services.

Logistics in trade has a pivotal role in the economic development and in the competitiveness of countries. This study aims to provide a strong empirical evidence in linking logistics performance with trade flows in the ASEAN region using panel data methods in an augmented gravity model. The Logistics Performance Index (LPI) collected by World Bank is the metric used for logistics performance whose impact on ASEAN’s aggregate and sectoral trade using the priority sectors from 2007 to 2016 is explored. For sectoral trade, the data is zero-inflated with a strong evidence of heteroscedasticity. Hence, non-linear methods were used, namely, Poisson Pseudo Maximum Likelihood method, Feasible Generalized Least Squares method, and the Heckman Two-step procedure, while for overall trade, the usual panel estimation methods were used. The results showed that logistics performance has a strong positive association with trade value, both for aggregate trade and for trade in each of the priority sectors. The outputs of the LPI framework, particularly, timeliness, tracking and tracing, and ease of arranging international shipments are relatively more important indicators of logistics performance in increasing trade value.

We describe a decentralized routing algorithm with physical time windows for modular conveying systems. Existing routing algorithms for modular conveyors are already capable of bi-directional conveying while avoiding conflicts such as collisions, deadlocks, livelocks and starvation effects. In addition to avoiding conflicts, routing algorithms must also select routes that reduce the travel time. No existing algorithm for modular conveyors bases this decision on the expected physical lead time, even though physical lead time directly affects the system throughput. In this publication, we present an algorithm that uses the physical lead time to select routes while avoiding conflicts.

This work investigates optimization techniques for a multi-period vehicle allocation problemwith uncertain transportation requests revealed sequentially over a rolling horizon. Policies derived from deterministic scenarios are compared: they are generated either by simple heuristics, or by more complex approaches, such as consensus and restricted expectation algorithms, or by network flow formulations over subtrees of scenarios. Myopic and a posteriori deterministic optimization models are used to compute bounds allowing for performance evaluation and for estimating the value of information. The economic benefit of the stochastic model is highlighted: our results show that the information about future, uncertain orders contained in the stochastic part of the horizon can be used to generate improved profits. Robustness against misspecified probability distributions is examined. Subtree formulations produce the best results, are robust and can be solved efficiently, which makes them appropriate for industrial implementations.

This paper introduces a new mixed integer model to provide efficient distribution plans to route a set of inbound/outbound heterogeneous vehicles in the crossdocking systems that are used to transfer different types of commodities from a manufacturing plant to retail warehouses with allowed split deliveries. The objectives are to minimize the total commodity deviations and the overall distribution time or cost of vehicles. Different data sets from different scales are randomly generated and solved by CPLEX-Concert Technology. As the proposed model is NP-hard; a new heuristic is constructed to solve the problem in reasonable computational efforts. Results show that CPLEX can obtain optimal solutions for small-scale sets and sub-optimal solutions for medium scale sets with a six-hour time limit, while it fails to provide any feasible solution for 35 out of 50 large scale sets. The proposed heuristic provides very competitive results compared to CPLEX in all scales in term of gaps and computational times.

Omni-channel retailers systematically connect their sales and communication channels to create a seamless shopping experience. Influencing customers in their channel choices can result in reduced costs to serve customers and increased revenue. To achieve this, comprehensive omni-channel customer management is necessary that also includes fulfillment processes during the customer journey. Operations plays a key role in omni-channel retailing as it is in direct contact with customers and does not end at the store like for bricks-and-mortar retailing. Omni-channel retailing and in particular customer management with fulfillment options is a new topic in practice and constitutes a new research area. The contribution of this paper lies in building a bridge between sales and operations between online and physical store retailing. We develop propositions that demonstrate how customers can be guided through the channels. We use an exploratory study where data are collected mainly from face-to-face interviews with 25 omnichannel retailers. The objectives of the research include identifying fulfillment-related customer management opportunities via multiple channels used by retailers, assessing the relationships and interdependencies of the customer management methods, and developing propositions for omni-channel customer management. The management options are related to questions such as how customers can collect availability information across channels, how purchase and payment processes are designed, how delivery speed and costs are defined, and which return options are possible. Findings include, among others, that retailers use product availability checks for guiding customers into the store, prioritize certain operational actions, and prevent product returns. If executed in the right way, omnichannel customer management will not only result in differentiation and cross-selling potential for retailers, but also in additional benefit for customers.

Due to changes in individual demand, manufacturing processes have becomemore complex and dynamic. To cope with respective fluctuations as well as machine breakdowns, capacity adjustment is one of the major effective measures. Instead of labor-oriented methods, we propose a machinery-based approach utilizing the new type of reconfigurable machine tools for adjusting capacities within a job shop system. To economically maintain desired work in process levels for all workstations, we impose a model predictive control scheme. For this method we show stability of the closed-loop for any feasible initial state of the job shop system using a terminal condition argument. For a practical application, this reduces the computation of a suitable prediction horizon to controllability of the initial state. To illustrate the effectiveness and plug-and-play availability of the proposed method, we analyze a numerical simulation of a four workstation job shop system and compare it to a state-of-the-art method. This article is the extension of a conference paper entitled ”Predictive Control of a Job Shop System with RMTs using EquilibriumTerminal Constraints” presented at the 6th International Conference on Dynamics in Logistics (LDIC2018).

Maritime transportation plays a leading role in the movement and minimization of transportation costs of goods between regions. One of the major challenges faced by port managers/operators is the growing number of containers or ship traffic which can affect the port container terminal productivity. Mathematical and simulation based models for berth assignments can help to solve such logistic problems in container terminals. However, existing simulation approaches are computationally intensive for optimizing the relevant factors that may affect the berth operation or port productivity. In this study, we propose a computationally efficient approach of combining simulation with Design of Experiments (DOE) to optimize the container port productivity. Further, based on a case study of container port terminal in Malaysia, we systematically examine the effect of tug pilots, berths numbers, cranes numbers and type of queue on port container terminal productivity. We found that only berth numbers, crane numbers and type of queue had significant effect on port productivity. It is recommended to adopt low container value, first serve queuing approach for serving the ships. We could achieve a maximum productivity of around 86% through our optimization model. Further, an increase of about 22% in port productivity as compared to the existing port productivity of the terminal was observed through our method.

The increasing construction of offshore wind farms and the expected improved profitability call for a better efficiency in offshore logistics. The purpose of this study is to propose scheduling and operations improvements for logistics to support offshore wind construction. The study conducts a literature review of scientific studies on the offshore wind logistics. Based on this review, a definition of offshore wind logistics during construction phase is proposed. It can be seen that only a few studies have focused on offshore wind logistics (except installation vessel) duringwind turbine construction phase. To help closing this gap, a model is proposed to evaluate and select offshore logistics spread in order to support construction phase. Results on simulations show that logistics spread efficiency varies depending on the season, distance to shore and geographical location. Adaptation and combination of logistics concepts may be necessary to achieve best cost efficiency. The results are important as a basis for further empirical studies in this area. At the end, we propose research areas for operational improvements.
