Timely responsiveness to the requirements of the organisation and an orderly supply in right quantities, with the right price for quality, from the right supplier, at the right time and place can never be achieved except through integration within every level of the organisation, namely suppliers, storage and distribution units, transportation and other logistics service sections. Bearing in mind the significance of integration in logistics organisations and bodies, this research defines a comprehensive concept on integration in logistics, investigates existing literature on the subject and further attempts to present an overarching conceptual framework and definition on supply chain and logistics integration will be made. In this regard, the present study initially investigates the definitive concepts in an array of domains and in particular, supply chain and logistics, and goes on to analyse past studies in terms of dimensions of integration, integration model, integration evaluation and case studies. Based upon the existing body of literature the present research then analyses the components of the logistics integration model in two domains of dimension and elements of integration and ultimately presents a conceptual model framework for logistics integration.
