Optimal Set

It has become widely accepted that delivering diverse products to customers who have different needs by a “one-size-fits-all” supply chain results in lower profits and customer service. Therefore, there is a need to design supply chain systems that can effectively and profitably serve products and customers with diverse characteristics. This paper presents a mathematical model that selects the optimal set of supply chains that match diverse characteristics of products and customers. The model considers various product, customer, and supply chain characteristics, including the required lead time, the supply chain lead times, the customer time sensitivity, and the complexity factor resulting from having multiple supply chains. An example and a sensitivity analysis are used to demonstrate the model's capabilities.

Supply Chain Costs

The effect of ‘supply chain management’ can be leveraged when benefits of collaboration within and beyond the capacities of individual organizations are witnessed. One of the primary tasks in reducing total supply chain costs is to understand where the costs occur in a supply chain and how each activity impacts the total supply chain costs. Most supply chains in construction usually involve multiple entities, each one in a different process. A rebar supply chain is one example where many entities are involved in different processes. The supply chain coordinator needs a supply chain cost model, which shows how each activity impacts all supply chain costs to reduce the total costs. The research suggests a supply chain cost model using time-driven activity-based costing. The proposed cost model was applied to a building construction project, followed by sensitivity analysis identifying critical activities. This method can be adapted to analyze other fragmented material supply chains in the construction industry.

AbstractLead times and their nature have received limited interest in literature despite their large impact on the performance and the management of supply chains. This paper presents a method and a case implementation of the same, to establish the behavior of real lead times in supply chains. The paper explores the behavior of lead times and illustrates how in one particular case they can and should be considered to be independent and identically distributed (i.i.d.). The conclusion is also that the stochastic nature of the lead times contributes more to lead time demand variance than demand variance.

Last Mile Delivery

With traditional ERP systems, there is a lack of networking among suppliers, partners, and logistics providers. So, there is a need to have a holistic view of production and movement of goods from production to last mile delivery. The physical and digital supply chains need to be integrated to ensure secure supply chains that promote business excellence, collaboration among stakeholders, and reduce costs. The high-level view over their supply chains allows them to function better in a multi-channel world. It also helps them identify where to reduce stock without compromising customer service. Otherwise, it leads to a delay in delivery, counterfeit products, thefts, fraud, and cyberpiracy, which may lead to lawsuits and losing of brand image. The tacit function of supply chain management is to provide tracking of specific goods in the supply chain. So, it is imperative to leverage the blockchain technology stack to map multi-enterprise value networks and enable connected multi-modal networks.

The aim of the presented work is to contribute to the field of the supply chain design that spans multiple organizations. It is based on a methodological approach that outlines two main results: a conceptual model and an operational one. These two models take into account the different characteristics and mechanisms of the supply chain. The conceptual level is based on four views: product, organizational, functional and informational. At this level, a meta-model that contains the basic generic concepts of the supply chain is proposed. The operational level uses the agent paradigm to model the different actors of the supply chain and the relationships between them. According to the characteristics of supply chains, a negotiation protocol between the different agents is presented. Simulations prove that the presented negotiation protocol can increase the efficiency and successful cooperation ratio for supply chain negotiation.

Financial Flows

Background: Global sourcing has impacted inventory levels, lead times and the availability of working capital, affecting the standard financial flow of a supply chain. Poorly managing the link between the financial and physical supply chains could therefore lead to unnecessarily high inventory investments or to a short supply of inventory, affecting cash flow, working capital, sales and, subsequently, a firm’s profitability.Objectives: The aim of this generic qualitative study was to explore how firms manage their financial supply chain alongside their physical supply chain.Method: Data were collected from 12 semi-structured interviews with senior managers across six small- to medium-sized enterprise (SME) importing firms in various industries.Results: The research finds that the buyer is the driver of both upstream and downstream financial supply chain management (FSCM) as SME importers in Gauteng are proactively managing their financial alongside their physical supply chains. Through the continuous evaluation of sourcing strategies, exchange rate risk management strategies and inventory investment management strategies, firms can align their physical and financial supply chains.Conclusion: This study highlights the lead time and disruption risks and costs of global sourcing and identifies FSCM tools that can be used to alleviate the financial burden associated with long lead times.

AbstractAs industries mature, they rely more heavily on supply chain management (SCM) to ensure effective operations leading to greater levels of organisational performance. SCM has been widely covered in many industrial areas and, in line with other burgeoning sectors such as Tourism, an industry focus provides the opportunity to look in-depth at the context-based factors that affect SCM. Developments in digital distribution and rapid technological innovations have resulted in an increased focus on Digital Supply Chains (DSCs), which bring about significant changes to how consumers, customers, suppliers, and manufacturers interact, affecting supply chain design and processes. Through a systematic review of the Videogames Industry Supply Chain Management literature, which serves as a pertinent contextual example of a DSC, we look at how supply chains are affected by structural, market and technological change, such as increased platformisation, disintermediation and the proliferation of digital distribution. We distil these findings into a new research agenda, which identifies themes in line with extant DSC research, provides a series of relevant practice recommendations and identifies opportunities for future research.

Proposed Model

Blending technologies play an important role in manufacturing. The design and operation of manufacturing processes using blending technologies represent a special range of manufacturing related logistics because the integrated approach of technological and logistic parameters is very significant. This research proposes an integrated model of supply of manufacturing processes using blending technologies. After a careful literature review, this paper introduces a mathematical model to formulate the problem of supply chain design for blending technologies. The integrated model includes the optimal purchasing strategy depending on the characteristics of components to be mixed in the desired proportion and the costs of supply. The integrated model will be described as a linear programming problem. Numerical results with different datasets demonstrate how the proposed model takes technological and logistic aspects into consideration.
