Management Levers for Product Platforms

Platforming has become an important means of cost-sharing among industrial products. However, many firms face systemic downward pressure on commonality, with the result that many platforms realize less commonality than intended. Past research has hypothesized that divergence is the result of conflicting tensions between product customization/optimization and cost control. This article investigates the control and incentive levers available to platform managers to shape the behavior of the organization when divergence opportunities arise. Management levers are drawn from a series of 12 industrial case studies, stemming from investigations of the causes of divergences. These management levers are categorized as technical levers, financial levers, and organizational levers. This article illustrates each of the management levers with examples from the case studies.     

Third-party apps (TPAs) and software platform performance: The moderating role of competitive entry

Noting the increasing importance of software platform, this article examines the effects of third-party apps (TPAs) on platform performance (PP) and how such effects differ before versus after competitive entry. The authors validate the hypotheses using data from the web browser market. The results show that the quantity of new TPAs leads to higher PP before than after competitive entry, whereas the quantity of TPA updates contributes a higher PP after than before competitive entry. In addition, the quality is more important and diversity is less important to PP after than before competitive entry.     

Modular product platform configuration and co-planning of assembly lines using assembly and disassembly

Formation of products platforms is carried out during the planning stage and very often separately from the planning of corresponding assembly lines. There is a dearth of literature which considers the different aspects of fully integrating platform design, product family formation, assembly line design, delayed product differentiation, and new concepts of mass customization. A Modular Product Platform Configuration model which uses assembly and disassembly for configuring product variants and Co-Planning of products platforms (MPCC) and their assembly Lines is presented. It is used to co-plan the common platform components and the associated product families simultaneously with the planning of its corresponding mixed-model assembly line. Using both assembly and disassembly to customize the product family platform in order to generate product variants is not commonly discussed in literature. It is defined as the formation of platforms for use to derive multiple products by including many components not shared by every product. The platform is then customized by assembling or disassembling components to form different product variants. The model is formulated using mixed integer mathematical programming to minimize the number of assembly stations and cycle time. Two case studies are used for verification and demonstration. They illustrated the ability of the MPCC model to integrate the planning of product platform, product families and the number of assembly stations required to assemble and disassemble components from mass-assembled product platforms to derive new product variants.     

马岭油田北三区延10储层宏观非均质性研究

马岭油田北三区延10储层主要发育平行层理、交错层理、斜层理等层理类型,韵律特征为多期次正韵律叠加;从上到下沉积相属于从曲流河相到辫状河相的过渡,从上到下小层非均质性增强,推测由于辫状河比曲流河河道变化更加频繁,沉积更加复杂导致;研究区平面上的非均质程度较强,对油田的实际开发生产影响程度较大。     

GeoReveal成像处理软件的开发及其应用

成像测井资料携带了丰富的井壁地层导电特性和声波传播特性的相关信息,与常规测井资料相结合可用于岩性识别、裂缝识别、薄层分析以及沉积构造研究等方面,特别是对于裂缝孔洞型储层的研究更具有独特优势。GeoReveal解释平台的声电成像处理软件,通过对成像资料预处理、数据处理、图像合成、图像动态增强、图像绘制、交互解释以及定量分析,来实现对各种构造和地质目标的解释评价工作。在川西北地区JLS构造下侏罗统珍珠冲段（3 287~3 300 m）砾岩储层的应用表明,该软件处理资料速度快,人机交互处理灵活,解释评价方便快捷,定量计算参数准确,比国内外同类软件有着更好的实用性。
