a software as a service with multi tenancy support for an electronic Contract Management application
IEEE International Conference on Services Computing, 2008Co-Authors: Thomas Kwok, Thao N NguyenAbstract:In most commercial electronic Contract Management applications available today, different customized code base has to be developed, deployed and operated to support each tenant. Few advanced commercial electronic Contract Management applications use a single code base with configuration options to support multi-tenants. However, a separate instance of the code base still has to be deployed and operated for each tenant even in these applications. The business model of having to support a single application instance for each tenant makes an electronic Contract Management application and other critical business applications out of reach for most small and medium businesses (SMBs), in particular, the very small businesses (SVBs) because of its high development and maintenance cost. Recently, a new business model of a single application instance supporting multi-tenancy based on software as a service (SaaS) has emerged making expensive business applications more affordable for SMBs and SVBs for multi-tenancy [1]. In this paper, we present the first of a kind multi-tenancy SaaS electronic Contract Management application. We also describe several novel methods used in the metadata, security and shared services, as well as customization and tenant extensions modules to support multi-tenancy SaaS in this application. This multi-tenancy SaaS application has shown to benefit both the application service providers as well as their tenants. This new multi-tenancy SaaS model can reduce the application hosting cost and make the application more affordable to the tenants because of its capabilities in customization and scalability while continuing to support an increasing number of tenants. It furthers benefits tenants by saving their money and time with immediate access to the latest IT innovations and infrastructure improvements on a single application code base. Most end users of tenants have found their productivities increased, the Contract transaction time accelerated, Contractual errors reduced in using this multi-tenancy SaaS electronic Contract Management application as demonstrated in several ongoing IBM pilot programs serving more than ten tenants with over 3000 end users.

a web based and email driven electronic Contract Management system
International Conference on e-Business Engineering, 2007Co-Authors: Thomas Kwok, Thao N Nguyen, Linh Lam, Trieu C ChieuAbstract:In an enterprise, managing and processing an electronic Contract often involves a number of Contract administrators and representatives in the enterprise, and their counter parts in their suppliers, business partners or their customers to carry out a large number of complex manual tasks in sequences during the life cycle of electronic Contract. In most commercially available electronic Contract Management systems, users either waste a lot of their time in monitoring their task lists for their turns to act on their electronic Contracts or most electronic Contracts simply stay idle for most of the time if users only check their task lists once a while. In addition, these manual tasks are often tedious and may cause security faults. In this paper, we present a Web-based and email driven electronic Contract Management system that supports both internal and intra-enterprises workflows, and with multi-tenants hosting capability. This system enables a user to act on the next task in a sequence of tasks to process a particular electronic Contract immediately after the other user has completed the previous task in the same sequence of tasks by sending out email notifications to alert or remind the user to take action on the task. We also describe several novel methods to automate some manual and tedious tasks, such as watermarking signature information on the signed electronic Contract and life cycle Management, in this paper. Most users have found their productivities improved, the electronic Contract transaction time accelerated, Contractual errors reduced and many other benefits by using this electronic Contract Management system in several IBM pilot programs.

an enterprise electronic Contract Management system based on service oriented architecture
IEEE International Conference on Services Computing, 2007Co-Authors: Trieu C Chieu, Thao N Nguyen, Sridhar Maradugu, Thomas KwokAbstract:Electronic Contract systems deal with the lifecycle automation and Management of Contract documents from their establishment to expiry. Many existing Contract systems are built as monolithic, vertical stand-alone applications that are inflexible and difficult to scale and interoperate with other enterprise systems. This paper proposes a service-oriented electronic Contract system that leverages a number of common middleware services to provide an open, extensible and interoperable solution. The basic common services include the content repository services, the workflow and document routing services, the security services, and the notification services. A standard data model is defined to specify the metadata properties for managing, tracking and storage of Contract documents in a central repository. Integration services are also introduced to enable the system to collaborate and share Contract data with external applications such as Contract authoring and fulfillment tracking tools. The implementation of an enterprise multi-party electronic Contract system using standard commercial middleware components will be presented to illustrate the simplicity, reusability, interoperability and flexibility of this service- based approach.

purchase Contract Management with demand forecast updates
Social Science Research Network, 2020Co-Authors: Hongyan Huang, Suresh Sethi, Houmin YanAbstract:We study a two-stage purchase Contract with a demand forecast update. The purchase Contract provides the buyer an opportunity to adjust an initial commitment based on an updated demand forecast obtained at a later stage. An adjustment, if any, incurs a fixed as well as a variable cost. Using a dynamic programming formulation, we obtain optimal solutions for a class of demand distributions. We also discuss how these results can be applied to gain managerial insights that help in making decisions regarding where to allocate efforts in improving the forecast quality and whether or not to sign a Contract.

A Blockchain-Driven Electronic Contract Management System for Commodity Procurement in Electronic Power Industry
IEEE Access, 2021Co-Authors: Lingling Guo, Qingfu Liu, Ke Shi, Yao Gao, Jia Luo, Jingjing ChenAbstract:In the era of paper-based Contract, a lot of time, human labor and expenses are required to handle the process of Contract drafting, Contract signing, Contract execution, and payment settlement. The emerging of electronic Contract enhances the tedious signing process of paper-based Contract and improves the efficiency of Contract Management. However, due to the centralized system architecture and the database-based storage schema, the stored Contract data is at high risk of information leaking, data tampering and hacker attacks. In this study, we introduce Blockchain technology to the Contract Management, and develop a process-oriented Contract Management system (BEContractor) for a Hangzhou-located power grid enterprise X, aiming to solve a series of security issues existing in the traditional electronic Contract system. By deploying BEContractor, procurement activities could be resumed online among X and its nation-widely commodity suppliers during COVID-19 epidemic. Up to September 2020, 6336 electronic Contracts have been signed, with an accumulated amount of $\yen ~6.5$ billion. It is showed that the cost for accomplishing the Contract signing process was significantly reduced, and the payment period was shortened from three months to around one month.
