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.

Climate Smart Agriculture Toolkit

Novel tool with graphic user interface used in India and parts of South Asia by the International Water Management Institute (IWMI). Toolkits for climate smart agriculture prioritization and food stock planning. Provides optimal land allocation decisions for crops, location of warehouses and distribution plan.

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:

Overlapping trips in case of BMTC were reduced to 0 from 4143
2309 redundant trips were removed from timetable
Effective redeployment of 1249 buses were done
Based on the effective redeployment 82 additional buses were available
Additional revenue of ~25.83 crores can be generated annually
~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

Sustainable Development Goals 2 (zero Hunger) Dashboard

SDG2-Rajasthan Dashboard

Objective:

To visualize the state, district and sub-district indicators and data for SDG 2 monitoring to enable evidence-based policymaking to support the efforts of Government of Rajasthan in achieving food and nutrition security in the state. “This includes embed tables, maps and other visualisation tools (Bar charts, Pie charts, Radar charts, etc.) in dynamic form, for SDG-2 vulnerability assessment at the state, district and sub-district level, in the dashboard developed on a user-friendly platform. The main expected outcome of this is to have robust SDG-2 dashboard that enables evidence-based monitoring and identification of vulnerable hot-spots for strategic planning and targeted action for achieving ‘Zero Hunger’ in the state of Rajasthan.

Development of SDG2-Dashboard

Front end of our SDG-2 dashboard is designed in ReactJS framework, and the backend is developed in PHP Language.

ReactJS is a declarative, fast, and adaptable JavaScript toolkit for creating user interface components. Facebook created ReactJS in its newsfeed area in 2011, but it was released to the public in May 2013.

Why we used React JS for front end design?

Helps in building high quality and rich user interfaces.
Fast rendering and high performance can handle complex and high loading apps.
Flexible and easy to maintain and allow writing custom components.
Strong community, third party open-source components easily available.

PHP (short for Hypertext Pre-processor) is the most widely used open source and general purpose server side scripting language used mainly in web development to create dynamic websites and applications. It was developed in 1994 by Rasmus Lerdorf.

Why we used PHP for backend design?

Gives Web Developer more control.
Database Connectivity.
