Thesis Title: Optimizing Bundling Strategies and Pricing Decisions in Supply Chain

In order to enhance sales and remain competitive against other firms and products, many businesses adopt a bundling strategy. Bundling is a selling strategy involving selling two or more products or services together.

In addition, with dynamic changes in the market, it is important for companies to set the right prices for their products and services. Thus, this research focuses on identifying bundling trends, including product and service bundling.

Furthermore, this research also investigates the bundling types and pricing strategies in the supply chain with several considerations and decisions that can optimize customer satisfaction, the performance of all of the entities in the supply chain, and the performance of the supply chain as a whole.

Thesis Title: Exploring an equitable approach to ‘social valuing’ social value in a public sector procurement contract: a multi-stakeholder supply chain perspective

This study explores the challenges of operationalising social value in the public sector commissioning and construction of the Shakespeare North Playhouse (SNP) in Knowsley.

The qualitative study explores how the awareness, understanding and measurement of social value and the UK Public Services (Social Value) Act 2012 is perceived across different stakeholders and governance levels in the SNP project.

The research uses the Multi-Level Governance framework to evaluate the participation and co-ordination between stakeholders and governance levels; their tensions and conflicts; and the dispersion of procurement decision-making processes related to social value. The data are used to develop a new fair and inclusive approach to ‘social valuing’.

Thesis Title: How could procurement activities impact modern slavery conditions in a UK construction supply chain

This research is an investigation into Modern Slavery from a procurement and supply chain management context. As globalisation has increased supply chains have become complex and as a result an organisation might only understand its tier 1 working conditions.

The scope of the research is to gain a better understanding between the links of modern slavery, supply chain management practices and other theories that might help prevent modern slavery conditions from arising.

Thesis Title: Revisiting Supply Chain Resilience Under Complexity Logic and Emergent Business Landscapes

My research is concerned with the concept of supply chain resilience, both theoretical and practical (implications) when considering "change and uncertainty" (as opposed to stability and equilibrium) as the normal state of working/living in the increasingly complex and globally interwoven business networks. The shortened periods between major global disruptive events, evidenced in the recent COVID-19 Pandemic, pose new and extensive risks to societies and the global supply chains as their economic channels of interaction.

Thesis Title: Role of Big Data Analytics in Improving the Performance of Humanitarian Operations

The use of Big Data Analytics is growing in profit-driven companies across all business functions. Could humanitarian organisations also make effective use of data analytics?

The research advances are essential considering the increase in the number of natural and man-made disasters and the rise in delays in the provision of assistance.

My work will examine how big data analytics can be used effectively in humanitarian relief operations and enhance coordination between stakeholders.

Thesis title: E-commerce Returns; Could Last-Mile Innovations Help Decarbonise the Reverse Network of Fashion E-commerce Retailers

An overwhelming 25% of the global e-commerce carbon footprint is owing to the reverse logistic process. In order to sustain the influx of product returns, retailers and logistic providers must endeavour to implement robust, innovative supply chain networks.

Reverse logistics, in particular, has the ability to increase the recovery value of returned products, prevent product decay and also ensure of safe disposal.

This research will investigate last-mile solutions in order to decarbonise the reverse network of fashion e-commerce retailers

Thesis Title: Barriers to delivering social value in public procurement?

The focus on public sector organisations to deliver value is intensifying. From January 2021 it became a requirement for all UK public procurement to give a minimum 10% weighting to social value in the tendering process.

This research focuses on the enablers to social value delivery by exploring the policy, systems, and practice constraints across the multiplicity of stakeholders within the supply chain. Challenges of public – private partnerships, the role of communities in delivering successful social value outcomes, and the effectiveness of governance will all be explored.

Thesis Title: Competition and coordination in agricultural supply chains under uncertainty

The agricultural sector plays a significant and vital part in not only contributing to economic growth but also reducing poverty.

There still are many operation management aspects in the field of agricultural supply chains (ASCs) requiring further investigation, for example, the change of power structure among ASC members, and various uncertainties from both demand and supply sides.

Therefore, this thesis aims to explore issues of competition and coordination in ASCs considering uncertainty.

Thesis Title: The Impact of New Product Introduction Delays on Stock Returns

Organisations must continually introduce new products to survive. However, all-too-often they are late to market; defined as not delivering on a promised introduction date based on a previous preannouncement. This research investigates the role of research and development on delays and the impact of delays on first-tier suppliers. This is done via a quantitative event study method which follows a systematic literature review.
