## 3. Problem Description

## 4. Methodology

- Phase 1: Sustainable and Resilient Supplier Selection

- ▪
- Step-1: Potential suppliers are evaluated based on TBL sustainability (economic, environment, social) and resilience criteria.
- ▪
- Step-2: Selection of sub-criteria for each sustainability and resilience criterion. (The sub-criteria have been included in Table 2.)
- ▪
- Step-3: Application of FE-AHP method to evaluate the relative weights of each supplier’s selection criteria.
- ▪
- Step-4: Application of FTOPSIS to rank the suppliers. (The linguistic variables used for calculating criteria weights and developing rankings of the suppliers are included in Table 3.)
- ▪
- Step-5: Preliminary selection of suppliers on the basis of defined thresholds of the closeness coefficient.
- ▪
- Step-6: A sensitivity analysis is performed to evaluate the robustness of the selected suppliers using the method identified by Forghani et al. [69].

- Phase 2: Order Allocation

- ▪
- Step-7: Identification of objectives for allocating optimal quantities to the potential suppliers. (The objectives are total cost, total travel time, environmental impact, acceptable quality limit, total value of sustainable purchasing.)
- ▪
- Step-8: Development of MOMINLP mathematical model along with demand, resource, and capacity constraints.
- ▪
- Step-9: Include uncertainty by developing the fuzzy MOMINLP mathematical model.
- ▪
- Step-10: Solve the model using nonlinear solver to determine minimum and maximum values of objective functions.
- ▪
- Step-11: Solve the model using AUGMECON2 and extract Pareto solutions.

- Phase 3: Best Solution Selection

- ▪
- Step-12: Use CRITIC method for determining objective functions’ weights for extracting best 10 Pareto solutions.
- ▪
- Step-13: Apply TOPSIS for the ranking of the best solutions for the time period considered.

#### 4.1. Development of Fuzzified Mathematical Model for Order Allocation

- Assumptions

- ▪
- The model is a multi-period model.
- ▪
- The shipments are considered as less than container load (LCL) shipments.
- ▪
- The transfer cost and transfer time can only be applied at the nodes.
- ▪
- The custom clearance cost and time can only be applied while moving through port.
- ▪
- Custom clearance can only take place at one port for a shipment, i.e., either at seaport or dry port.

## 6. Discussion

## 7. Managerial Insight

- (a)
- A multi-phase, multi-period smart decision support framework has been proposed for sustainable and resilient supplier selection and order allocation. The proposed framework has been demonstrated using real-time data collected from the pharmaceutical industry.
- (b)
- A combination of TBL sustainability and resilience criteria has been employed for supplier selection and order allocation that leads to a more comprehensive and thorough evaluation of the sustainable and resilient supplier selection and order allocation problem.
- (c)
- A detailed fuzzified mathematical model has been developed for order allocation. As demonstrated by the results presented in the preceding sections, this mathematical model can successfully handle real-life uncertainty of decision variables during supply-chain operations.

## 8. Conclusions and Future Recommendations

- (a)
- Among the TBL sustainability criteria, product price, past business, innovative capability, and information disclosure rank as the most significant sub-criteria for the DMs in the pharmaceutical industry.
- (b)
- Robustness and flexibility are considered the most valued attributes in the potential suppliers as far as the resilience criterion is concerned.
- (c)
- The transfer cost and custom clearance cost comprise 69.4% of the total cost of the supply chain network. On the other hand, transfer time and custom clearance time comprise only 24.7% of the total transportation time.
- (d)
- Transportation by sea has the least impact on environment (8.2%) while transportation by rail has the highest rate of environmental impact (62.5%) followed by transportation by road (29.5%).
- (e)
- Inland transportation of goods is dominated by rail as the most preferred mode of transport. Transportation by rail is also preferred by potential suppliers located in geographically contiguous countries.
