In this paper, a mathematical model is developed to calculate the conversion and the residence time reaction for plug flow and mixed flow in the reactors filled with cylin-drical particles using the shrinking core model. In this modeling, the size of the particles is un-chamged during the reaction. Also, the reaction rate is controlled by the gas layer resistance, the ash layer resistance, and ...

Supply chain management (SCM) has rapidly emerged as the central field of competition in many industries and has captivated the top executives of companies in the recent past. Electronic commerce (EC) technologies have the potential to revolutionize how firms coordinate and manage their supply chain activities. This paper focuses on the emerging paradigm of Internetenabled supply chain manageme...

Since its introduction by management consultants in the early 1980s, supply chain management (SCM) has been primarily concerned with the integration of processes and activities both within and between organisations. The concept of supply chain integration (SCI) is based on documented evidence that suggests that much of the waste throughout businesses is a consequence of fragmented supply chain ...

Organizations invest heavily in Customer Relationship Management (CRM) and Supply Chain Management (SCM) systems, and their related infrastructure, presumably expecting positive benefits to the organization. Assessing the benefits of such systems is an important aspect of managing such systems. Given the substantial differences between CRM and SCM systems with traditional intra-organizational a...

Combining with the collaborations between business customers and suppliers, traditional purchasing and logistics functions have evolved into a broader concept of materials and distribution management, namely, supply chain management (SCM) (Tan, 2001). This chapter reviews the literature of SCM from several paths that can be the basis of a proposed framework for SCM within academic and manageria...

Modeling of adsorption phenomena was carried out for core-shell adsorbents with spherical, cylindrical, and slab-type morphologies. Numerical solutions adsorbates in the adsorber could be obtained as a function time by solving coupled diffusion equations to take account inert-core thickness (x’). Transient responses batch continuous adsorbers containing were predicted, assuming rectangular or L...

The constant-ratio rule (CRR) and four interpretations of R. D. Lute’s (In R. D. Lute, R. R. Bush, & E. Galanter (Eds.), Handbook ofmathematicalpsychology (Vol. 1). New York: Wiley, 1963) similarity choice model (SCM) were tested using an alphabetic confusion paradigm. Four stimulus conditions were employed that varied in set size (three, four or five stimulus elements) and set constituency (bl...

This paper criticizes traditional models of urban–regional expansion, which depart from monocentric ideals urban core and ring. The original spatial-cycle model (SCM) suggests repeating stages urbanization, suburbanization, disurbanization re-urbanization. We reconceptualize the relations between core(s) ring(s) to test formation regions under mono-, multi- polycentric trajectories. analysis em...

Software Configuration Management (SCM) can be defined as the control of the evolution of complex software systems. It is a supporting software life cycle process that benefits several activities of the software process. SCM proved to be one of the most successful software engineering technologies, and there are many tools available to support it. In spite of that, SCM has some challenges to fa...
