INTRODUCTION The process of transporting critical supplies post the disaster is very complex. It is therefore required that the relief operation must be very efficient and appropriate to match the requirements of the situation. Three structures of Post Disaster Humanitarian Logistics (PD-HL) Operation namely, Agency Centric Efforts (ACEs), Partially Integrated Efforts (PIEs) & Collaborative Aid Networks (CANs) Question arises in the superiority of these structures, one over the other. It is very important to choose the appropriate post disaster humanitarian logistics structure. An evaluation framework is required, which should incorporate all the determinants of these structures and is useful to select to most appropriate structure.

DETERMINANTS of PD-HL STRUCTURES SPEED AGILITY ADAPTABILITY DECENTRALIZATION RESILENCE ALIGNMENT INFORMATION SYSTEM RESOURCE AVAILABILITY Some important PD-HL determinants are identified. There are eight determinants:

DETERMINANTS of PD-HL STRUCTURES SPEED The aid supply network in disaster relief is characterised both by its speed of inception and execution, as well as their relative impermanence. it serves a common goal an important characteristic in team formation AGILITY Quick response to change, As post catastrophic events, agility is very essential, since nobody knows that what challenges the relief operation is next going to face ADAPTABILITY As the situation changes, the PD-HL structure must be able to respond to the demand of the situation in the most appropriate way DECENTRALIZATION very important to reach the affected locations simultaneously as impacted area can be severely affected from various locations

DETERMINANTS of PD-HL STRUCTURES RESILENCE There are risks such as operational risks and functional risks which can arise during the relief operation, so the structure must be resilient enough to respond to ever changing situation. ALIGNMENT Any relief operation is interlinked with various activities and processes. If the goals for the effective relief are not aligned, then any operation cannot work in the desired way. INFORMATION SYSTEM As the experience in many past disasters has demonstrated, a successful local delivery operation requires not only logistical structure, but also information systems. RESOURCE AVAILABILITY The resource available gets exhausted continuously in any relief operation. So the resources must be checked regularly and replenished as required.

Alternatives for Structuring Post Disaster Humanitarian Logistics Operation Agency Centric Efforts (ACEs) Operation is based on the internal capacities of the group. This mainly comprises of the individuals and groups who are from the communities affected from disaster.. This is based on the internal capacities Partially Integrated Efforts (PIEs ) Group members can be local This structure is internally strong and could be well connected to the locals. The foreign group along with some locals helps with the local distribution of the supplies Collaborative Aid Networks (CANs) Comprises of social and religious groups The relationship to local people is very strong. The knowledge of the local conditions is very extensive. The strength of the network is very strong

Decision Environment Analytic Hierarchical Process a multi-criteria decision-making technique takes both quantitative and qualitative data into account involves the principles of decomposition, pair-wise comparisons, and priority generation and synthesis. based on the reasoning, knowledge and experience of the experts in the field

Agility (0.219) is the most important criteria in the selection of any post disaster humanitarian logistic structure.

Conclusion  The AHP model presented in this paper structured the problem of selection of the structure for post disaster humanitarian logistic operation.  AHP model integrates both quantitative and qualitative aspects and aids the decision makers in arriving at the best possible solution. Limitations  The formation of pair-wise comparison matrices and data acquisition is a tedious and time consuming task  Biasing might have influenced the results as they are based on the opinion of the experts  We have tried to minimize this by checking the consistency of comparison using the method of consistency ratio
