Global Supply Chain Route Optimization

The Public Systems Lab, IIT Delhi is actively engaging with relevant stakeholder discussions in order to scale up the route optimization project, which is being implemented by the Government of India across the country, internationally.

Industrial Corridor Optimization

The Public Systems Lab, IIT Delhi in collaboration with Government agencies like the National Industrial Corridor Development Corporation (NICDC) have initiated discussion for a joint project which revolves around the optimization and validation of 10 identified locations for Industrial Corridor Projects. Specifically, the focus is to demonstrate the optimality of the pre-selected sites. This involves evaluating relevant factors such as logistics and production costs.

Objectives:

  • To showcase the optimality of the ten pre-identified locations for Industrial Corridor Projects.
  • To integrate the Gatishakti portal in the assessment process and leverage the portal’s data and features to enhance the evaluation of transport and other related factors.

Methodology:
In this study, we employ a robust methodology to assess the optimality of the pre-identified locations for Industrial Corridor Projects. The approach uses two powerful analytical techniques: data envelopment analysis (DEA) and analytic hierarchy process (AHP). DEA, a non-parametric method, enables us to evaluate the relative efficiency of each location based on multiple criteria. It allows us to determine which locations are performing optimally in relation to the others, considering various inputs and outputs. Complementing DEA, AHP aids in prioritizing and weighing the significance of each criterion.

PSL Millet Systems

Building up on the ongoing research & development and responding to the global
needs around better health & environment and the context of the International
Year of Millets, the Public Systems Lab (PSL) at IIT Delhi has initiated the ‘PSL
Millets Programme’ with the objective of increasing demand and access,
improving supply chain, boosting awareness and supporting millet-based value
chains. Funds are being sought for the following:

Millet Subscription Model and pilot: Millet subscription will cater to the population segment that is interested in millets but needs better access to regularize consumption and concretize demand. Like other services in the digital economy, the core idea of this project is to develop a consumer portal for delivery of millet products and make the business sustainable through Operations Research based optimal pricing. Working stages of the project
includes:

  1. Development of Millet Access Platform (MAP): a user-friendly subscription portal
  2. Research-based model development to address user concerns & optimal pricing
  3. Pilot in limited geography such as IIT Delhi
    Results of our ongoing research indicate a significant (50%+) willingness to subscribe. Ongoing work also includes designing targeted outreach and identifying farmer suppliers.

Nudge Study: The importance of PDS in pushing wheat and rice to alter the consumption pattern across the country is widely acknowledged. This part will design and study the impact of nudges for promoting millets among PDS consumers. Key work elements include:

  1. Study and analysis of the consumer perception amongst PDS customers about millets
  2. Introduction of nudges at selected Fair Price Shops
  3. Assessment of impact of nudges on millet purchasing behaviour in a nearby state

Further, in the short to medium run, we also envisage the PSL as a hub for conducting empirical research on the issues pertaining to public good and economic policy which are well aligned with global priorities as envisaged in the Sustainable Development Goals (SDGs), particularly SDG-2 (zero hunger, and better nutrition, since millets can grow in relatively infertile areas and at low scale for global as well as local communities), SDG-3 (good health & well-being, since millets have well established health benefits), SDG-11 (sustainable communities, since millets contribute to healthier soil), SDG-12 (responsible consumption & production, since millets use significantly lesser water than other grains), SDG-13 (climate action, since growing millets can fight climate issues) and SDG-17 (partnerships, since millets are traditional livelihood enhancers and the project approach incorporates partnerships between academia, entrepreneurs, farmers and consuming communities in rural as well as urban areas).

Food grain Supply-Chain planning & optimization across Indian states

Food Grain Supply Chain Optimization across Indian states

PURPOSE 

Foodgrain supply chains are one of the few determinants of food security of India’s poor and vulnerable sections Lapses in these supply chains, as the entire world is realizing due to current Geopolitical circumstances:

  • potentially undermines the national food security scenario
  • causes wastage due to storage and transit deficiencies 

The central government has adopted several plans and schemes such as ‘end to end computerisation of TPDS operations’ to upgrade monitoring and avoid fraudulent beneficiaries. However, none of this directly address supply chain efficiencies. Accordingly, our project addresses the following challenges: 

  • grain overflow issues arising due to greater procurement for lower storage capacity
  • regular transportation in hilly terrains affected by climatic conditions 

Overall, making the supply chain logistics more efficient & effective by reducing cost and enhancing access.

PROJECT

States incur high transportation costs for TPDS due to difficult terrain, limited resources, restricted windows for transportation and disintegrated storage spaces. To address this and ensure pre-prepositioning of adequate safety stocks in the areas where access is affected by seasonal and predictable hazards, the Public Systems Lab supports the states through supply chain optimization. An Operations Research (OR) based mathematical programming model helps minimize the total transportation cost while incorporating all practical conditions to make it implementable. 

Outcome:  

WAY AHEAD

The PSL currently is building supply chain optimization models in all states across the country based on their specific requirements. As already demonstrated, our strategically planned modeling interventions will:

  • respond to the challenges and contingencies of different states
  • drastically reduce the levels of food wastage, while effectively meeting the needs of all targeted beneficiaries
  • reduce the cost of transportation for the government, and
  • expand to include allied logistical challenges as required by the states

Our team will have experts from academia (IITs) and a strong partnership with the leading multilateral organization in this area, the United Nations (UN) World Food Programme (WFP). Leveraging expertise from various stakeholders, as required, the project team will increase efficiency and effectiveness in PDS.

Bus Operations Toolkit (BOT)

Introduction to the project:

For every city public transportation plays an important role in its growth. It important to have the reliable public transport service and cater the service demand of the city. A city can have widespread route network, and PT agency with large bus fleet size operates through its different depots. Due to this depot-based scheduling of the buses, final timetable of the buses can have a different problem like overlapping of trips, inconsistent headway, and underutilization of the buses.

In our project, we have identified this issue in the current timetable of Bangalore Metropolitan transport corporation (BMTC), which is one of the India’s largest public transport service providers. BMTC has 6565 buses operating on 2203 different routes across the city. The daily number of trips done are 47353.

Our objective for the project is:

  • To remover the overlapping trips from the timetable i.e., overlaps are defined as multiple trips by different buses from same origin to destination following the same route.
  • To ensure the proper breaks after each trip
  • To increase the bus utilization and improve the service reliability.

Representation of overlapping trips

After analyzing the dataset provided by BMTC we found out that given schedule has total 4143 overlapping trips, and almost 50% of the buses are involved in the overlaps. We have represented the hourly band wise overlaps as below:

 

To address this issue a toolkit is developed with the following approach:

A desktop-based toolkit using the python code is developed, which follows the operation research techniques for the optimization and effective utilization of the bus fleet. GUI of the toolkit looks like follows:

As we can see in the above GUI, a toolkit needs only four inputs, 1. Current schedule of the buses in excel file format 2. Minimum safety headway allowed in minutes which is used for the rescheduling of overlapping trips 3. Maximum running hours of bus in day and 4. Maximum travel time to go from one bus stop to another across the city

 

Impacts and benefits:

Following are the direct impacts:

  1. Overlapping trips in case of BMTC were reduced to 0 from 4143
  2. 2309 redundant trips were removed from timetable
  3. Effective redeployment of 1249 buses were done
  4. Based on the effective redeployment 82 additional buses were available 
  5. Additional revenue of ~25.83 crores can be generated annually
  6. ~48,000 daily i.e., 1.75 crore additional passenger trips can be added in the timetable

Welfare benefits:

 

Smart Warehouse

                    IoT based SMART WAREHOUSE

 

PURPOSE

A substantial amount of post-harvest food grains wastage in India (about 10%) is due to:

  • widespread inadequacy in storage and infrastructure capabilities. With 
  • more produce than the available amount of storage space available across the nation. 

It therefore becomes a challenge to adequately, preserve and handle foodgrains with minimum spoilage. Keeping these concerns in mind, the IoT based smart warehouse is based on state of the art technology

PROJECT

Internet of Things (IoT) based Smart Warehouse is highly effective mechanism of foodgrain storage management and will ensure rightful utilization through structured monitoring of various parameters in real time. The warehouse is equipped with state-of-the-art technology like temperature sensors, air quality sensor, passive infrared motion sensors for rodents, phosphine fumigation sensor, missing bag identification and many more. It aims to achieve a significant reduction of food wastage caused due to traditional storage practices while identifying the sources of waste to develop further solutions against foodgrain losses. The project also enables:

  • Dashboard & mobile-based app linked to warehouses & integrated to Supply Chain Management systems used for the TPDS & procurement operations
  • Set-up Mobile Storage Units (MSU) and assess impact on loss reduction 
  • eLearning solution for anytime access to global best practices in warehouse and post-harvest management                                                                              

OUTCOME 

  • Effective storage and distribution of foodgrains 
  • Significant food waste reduction
  • Real time monitoring of activities in warehouses

                                                                                                                                                            GUI- Monitoring

The IoT based Smart Warehouse apart from the above-mentioned outcomes will also impact a number of stakeholders ranging from the National/state/district officers to the farmers:

  • Data driven policy formulation & drill down view of warehouse operations for Government officials
  • Enable data driven planning, performance analysis and corrective recommendations
  • Access to updated information & input/output market channels for Farmers

The Public Systems Lab looks forward to repeat the installation of Smart Warehouses across all the states of India. Multiplying the deployment of smart warehouses will:

  • Show tremendous results in terms of checking and controlling foodgrain wastage 
  • Skills and manpower in demand will increase scope for employment
