Application and evaluation of packaging postponement strategy to boost supply chain responsiveness: a case study

The purpose of this study is to demonstrate how packaging postponement can be effectively leveraged in a dynamically changing diverse retail market where responsiveness is key. The study also guides about the empirical evaluation of how packaging postponement affects the performance in the sanitary pads supply chain by considering operating measures. The focal company belongs to the Indian Fast Moving Consumer Goods sector, hygiene products category. It examines the measures that are critical to a responsive supply chain and presents a comparative analysis of selected measures before and after implementation. The findings illustrate that the packaging postponement not only improves competitive advantage but also significantly contributes to improving product proliferation and supply chain responsiveness. The study provides understanding of drivers and obstacles for packaging postponement strategy with operational insights about ‘how-to’ implement. Most of modelling-based research studies justify the adoption of postponement through savings in inventory only and underplay on other operating measures. While justifying, studies emphasise ‘form’/manufacturing aspects and underestimate the packaging aspects of postponement. This paper addresses these gap areas by systematically highlighting prerequisites and demonstrates the benefits of adopting a packaging strategy to handle variety and responsiveness in an emerging economy.     

On irreducible no-hole <Emphasis Type="Italic">L</Emphasis>(2, 1)-coloring of subdivision of graphs

An L(2, 1)-coloring (or labeling) of a graph G is a mapping \(f:V(G) \rightarrow \mathbb {Z}^{+}\bigcup \{0\}\) such that \(|f(u)-f(v)|\ge 2\) for all edges uv of G, and \(|f(u)-f(v)|\ge 1\) if u and v are at distance two in G. The span of an L(2, 1)-coloring f, denoted by span f, is the largest integer assigned by f to some vertex of the graph. The span of a graph G, denoted by \(\lambda (G)\), is min {span \(f: f\text {is an }L(2,1)\text {-coloring of } G\}\). If f is an L(2, 1)-coloring of a graph G with span k then an integer l is a hole in f, if \(l\in (0,k)\) and there is no vertex v in G such that \(f(v)=l\). A no-hole coloring is defined to be an L(2, 1)-coloring with span k which uses all the colors from \(\{0,1,\ldots ,k\}\), for some integer k not necessarily the span of the graph. An L(2, 1)-coloring is said to be irreducible if colors of no vertices in the graph can be decreased and yield another L(2, 1)-coloring of the same graph. An irreducible no-hole coloring of a graph G, also called inh-coloring of G, is an L(2, 1)-coloring of G which is both irreducible and no-hole. The lower inh-span or simply inh-span of a graph G, denoted by \(\lambda _{inh}(G)\), is defined as \(\lambda _{inh}(G)=\min ~\{\)span f : f is an inh-coloring of G}. Given a graph G and a function h from E(G) to \(\mathbb {N}\), the h-subdivision of G, denoted by \(G_{(h)}\), is the graph obtained from G by replacing each edge uv in G with a path of length h(uv). In this paper we show that \(G_{(h)}\) is inh-colorable for \(h(e)\ge 2\), \(e\in E(G)\), except the case \(\Delta =3\) and \(h(e)=2\) for at least one edge but not for all. Moreover we find the exact value of \(\lambda _{inh}(G_{(h)})\) in several cases and give upper bounds of the same in the remaining.     

Hybrid organization deconstructed: A bibliographic investigation into the origins,development, and future of the research domain

Research on hybrid organization (HO) has grown rapidly over recent decades, yet the conceptualization and research structure remain fragmented. In this paper, we employ a combination of bibliometric analysis and a structured review of recent influential articles to evaluate the domain of HO. As part of the bibliometric analysis, we analysed 676 documents containing 51,014 references by applying citation, co-citation, and social network analysis (SNA) techniques. Based on our analysis, we identified the 108 most influential works shaping the domain and explored the linkages between them to uncover the intellectual structure of the domain. Specifically, we observed five different clusters that depicted the intellectual structure of the HO domain. Our result further clarified the overall centrality features of the HO research network. Further, the structured review resulted in the identification of six different themes: impact of organizational actors on HO, impact of the external environment on HO, hybridization process and organizational response, organizational structure and governance, organizational strategy, and organizational performance. Building on our results, we propose a framework and explicate the gaps for future HO research.
