Case Study about Joint Online Truck Scheduling and Inventory Management for Multiple Warehouses
Abstract:~ For a true issue —transporting beds between warehouses to certification suﬃcient supply for known and extra stochastic interest —we propose a result methodology by means of arched unwinding of a number modifying plan, suitable for online advancement. The fundamental new component joining tracking and stock administration is an arched piecewise direct cost capacity that is dependent upon minimizing the normal number of beds that still need transportation. For speed, the raised unwinding is fathomed pretty nearly by a bunch methodology yielding an online lineup in 5 to 12 minutes for up to 3 warehouses and 40000 articles; interestingly, processing times of state of the craft Lp-solvers are restrictive for online provision.
Introduction:- Acknowledge the accompanying genuine issue. Given numerous warehouses associated by a shuttle administration of some trucks for delivery beds of saved articles between them; given additionally an online stream of requests, that are stochastic in nature and that must be took care of inside brief time at speciﬁc warehouses. Right conceivable to give, on the web, a timetable of truck tracks and truck loads for the purpose that all items are accessible at the opportune place in advance of handling time regardless of the possibility that the acknowledgement of the agenda is liable to further questionable matters? We propose a result approach dependent upon curved unwinding and show its useful suitability on certifiable information of our streamlined friend ecom Logistik Gmbh & Co. Kg. For up to three warehouses and about 40000 articles the system figures a timetable inside ﬁve to twelve minutes. Keep reading…
Study about Joint Online Truck Scheduling and Inventory Management for Multiple Warehouses
Abstract: For a real world problem transporting pallets between warehouses in order to guarantee suffcient supply for known and additional stochastic demand we propose a solution approach via convex relaxation of an integer programming formulation, suitable for online optimization. The essential new element linking routing and inventory management is a convex piecewise linear cost function that is based on minimizing the expected number of pallets that still need transportation. For speed, the convex relaxation is solved approximately by a bundle approach yielding an online schedule in 5 to 12 minutes for up to 3 warehouses and 40000 articles; in contrast, computation times of state of the art LP-solvers are prohibitive for online application.
Introduction: Consider the following real world problem. Given several warehouses connected by a shuttle service of several trucks for shipping pallets of stored articles between them; given also an online stream of orders, that are stochastic in nature and that have to be handled within short time at speciﬁc warehouses. Is it possible to provide, online, a schedule of truck routes and truck loads so that all products are available at the right place ahead of processing time even if the realization of the schedule is subject to further uncertainties? We suggest a solution approach based on convex relaxation and demonstrate its practical suitability on real world data of our industrial partner eCom Logistik GmbH & Co. KG. Keep reading…
Since our first audits in 2006, we’ve expanded to more countries and more supplier categories. We’ve conducted audits in 14 countries, and in 2012, our audits covered nearly 1.5 million workers. We also perform audits in select nonproduction facilities, including call centers and warehouses. In addition, we conduct specialized audits focusing on areas such as the environment and safety.We audit our final assembly manufacturers annually, and we audit other facilities based on certain risk factors, including location and geographic sensitivities, past audit performance, and the nature of the facility’s work. Since many smaller suppliers have never been exposed to auditing, our audits often identify ways to enable operations to comply with our standards. This effort not only improves working conditions at these suppliers, it also helps improve conditions industrywide, since many of our peers use the same companies.
Core violations and corrective action: Apple considers the most serious breaches of compliance to be core violations. These include physical abuse; underage, debt-bonded, or forced labor; falsification of information or obstruction of audit; coaching workers for audits or retaliating against them if they provide information; bribery; significant pollution and environmental impacts; and issues posing immediate threat to workers’ lives or safety. All core violations must be stopped and corrected immediately. Our preference is to fix problems so they don’t happen again rather than just fire the supplier—which would likely let these violations continue for other customers. However, if a violation is particularly egregious, or if we believe a supplier is not fully committed to stopping the behavior, we terminate our relationship with that supplier and, when appropriate, report the behavior to the proper authorities.

This Six Sigma case study looks at how we were able to drastically reduce inventory levels for our client in the oil and gas industry. This was done without sacrificing service levels.
The Problem:In this six sigma case study, we look at a large company in the oil and gas sector that sells drilling liquids and chemicals to exploration companies.
The supply chain path of the company worked like this:
Product Manufacturer –> Regional Hub –> Country Warehouse –> District Warehouse –> Rig Storage
Since the items on the rig were on consignment, technically the inventory was still owned by the supplier until it is actually consumed by the customer.
Oil drilling can be highly variable and if for some reason the rigs run out of drilling fluids, it could cost the drilling company millions of dollars per hour. Due to this fact, the fluids company stocked multiple times of what was actually required to ensure they do not ever face that situation.
The inventory turns were at 1.2. This means that on average, a product would sit around for about 10 months before being consumed! These were high value and bulky items which required large warehouses to host them. Click here to read more…

The Book Service (TBS) is the book distribution arm for leading UK publisher The Random House Group and is the UK’s leading trade book distributor. TBS distributes books for its parent Random House Group and also for a number of well known third party UK book distributors including Virgin, Little Brown, the AA, Faber and Faber and Lonely Planet books. The division plays a crucial role for the UK’s publishing industry – with over 24 percent of UK trade publications distributed by them every year.
The distribution division operates using four warehouses across Britain. The three warehouses at Colchester, Grantham and Wellingborough distribute the books while its returns warehouse is located in Manningtree. TBS operates 24 hours a day between Monday and Saturday to deliver books to key High Street retailers including WH Smith, Waterstones and Books etc. Working together, the distributor’s warehouses send out a phenomenal 100 million books per year across the UK and globally, comprising up to 45,000 different titles.
From Green Screens to the Web
At the forefront of book distribution in the UK, TBS has continuously invested in technology, allowing it to improve service, maximize efficiency and minimize cost. A key part of their service is their core ERP solution called Vista which has formed the backbone of the organization’s IT systems for nearly 30 years. Within Vista, users were required to access information via green screens.
As the demand from customers grew and the subsequent volume of books that TBS needed to distribute increased, a replacement for the old green screens application was required. It needed a web-based system that was easy to view and use and which could easily be accessed remotely by clients based at home or on the road.
Jai Balaji Group proposed to develop a web based purchase and stock management system where in they can automate and maintain the procurement process and also manage inventories of different items at different warehouses across various divisions in different locations. The solution would be hosted and run from Java enabled 3rd Party remote hosting service provider and would be accessed from the company’s head office in Kolkata and also from different divisional offices / factories situated across different geographic locations through available internet connection via web browser such as internet explorer.

“I don’t think I’ve ever had a question from anybody in the organization where I wasn’t able to find the data and give them something meaningful from which they could make a good business decision. In my mind, that’s the most you could ever ask for in a system.”
- Craig Thackray, Information Technology Manager, Bristol Group Ltd.
Business Challenge: Bristol’s management found that its ability to move quickly and confidently was limited by an aging retail solution. The decade-old system was originally designed for the food industry but had been extensively customized for use in the spirits industry. Although it was capable of handling Bristol’s heavy transaction volumes, the system wasn’t able to provide the volume or depth of information Bristol’s managers sought for clear insights into the business. For instance, the system allowed Bristol’s IT department to create only a handful of standard reports…
Solution: To address Bristol’s needs for a more modern system that could provide outstanding management information, the company selected Tectura to implement a new retail solution based on Microsoft Dynamics NAV and LS Retail NAV.The solution was deployed to Bristol’s head office, retail stores and warehouses over several months. Tectura implemented the system in a distributed database environment, running on a Microsoft® SQL Server™ database. Each of Bristol’s 17 stores and three warehouses has its own database, which synchronize with a more robust database in Bristol’s head office…
