Abstract

Purpose

This paper aims to propose a new ten-transistor (10T) SRAM bit-cell with differential read and write operations. The cell structure has read buffer on each side of the cell to improve read performance and comprises six main body transistors’ connections similar to the commercial 6T SRAM cell to improve write performance. The proposed bit-cell is designed with tri-gated FinFET technology and implemented on a silicon-on-insulator (SOI) substrate. 3D TCAD simulations are performed to characterize the efficacy of the proposed bit-cell. Performance characteristics of the proposed bit-cell are compared with the recently reported 8T bit-cell as well as the commercial 6T cell. The proposed bit-cell achieves 26.50 per cent and 35.10 per cent higher read static noise margin (RSNM) as compared with that of 8T and 6T bit-cells, respectively, at a VDD of 0.9 V. The proposed bit-cell also offers 54.78 per cent and 21.18 per cent smaller read delay compared with 8T SRAM-NEW and 6T bit-cells, respectively. The static power dissipation of the proposed bit-cell is comparable with that of the 6T bit-cell and 24.5 per cent lesser compared with that of the 8T bit- cell. The overall electrical quality of the SRAM circuit with the proposed bit-cell is enhanced up to 1.673 times and 1.22 times as compared with the 8T SRAM-NEW and 6T bit-cells, respectively.

Design/methodology/approach

A new 10T SRAM bit-cell with differential read and write operations is proposed. The proposed bit-cell is designed with tri-gated FinFET technology and implemented on an SOI substrate. 3D TCAD simulations are performed to characterize the efficacy of the proposed bit-cell. Performance characteristics of the proposed bit-cell are compared with the recently reported 8T bit-cell as well as the commercial 6T cell.

Findings

The proposed bit-cell achieves 26.50 per cent and 35.10 per cent higher RSNM as compared with that of the 8T and 6T bit-cells, respectively, at a VDD of 0.9V. The proposed bit-cell also offers 54.78 per cent and 21.18 per cent smaller read delay compared with the 8T SRAM-NEW and 6T bit-cells, respectively. The static power dissipation of the proposed bit-cell is comparable with that of the 6T bit-cell and 24.5 per cent lesser compared with that of the 8T bit-cell.

Abstract

Purpose

The ability of an organization to observe varying demands and efficiently meet them can be described as agility. Project procurement management (PPM) in the past was stable as things did not change very often and were very predictable. Due to hyper-competition, less predictable market and exponential innovation, the existing PPM becomes very unstable which marks the requirement of an agile model to manage procurement projects effectively. The paper aims to discuss this issue.

Design/methodology/approach

For achieving the improvements, various barriers to improving agility in PPM were identified from the literature and experts’ review, followed by obtaining quantified impacts of identified barriers from the experts using the Delphi technique. Finally, interpretive structural modeling along with Matrice d’ Impacts Croises Multiplication Appliqué an Classement analysis was used to analyze the interactions among barriers to prioritize and strategize their mitigation.

Findings

As per the analysis, the lack of top management alignment and commitment, lack of digital strategy, lack of new technology competencies and inefficiencies of financial factors were the most critical barriers that would come across while improving agility in PPM for any organization. Industries should have a stable, well-established and supportive top management that has a vision for digital transformation along with upgrading the companies’ technology layer for automating most of the manual processes to have intelligent decision-making capability.

Originality/value

Industries need to be agile in their operations for being more competitive and responsive to the market. PPM being the most critical part of the entire value chain needs to be agile in the first place. The strategies developed as an output of this research can be utilized by industries for improving agility in their business processes.

Abstract

Purpose

In the existing era, the Internet of Things (IoT) can be considered entirely as a system of embedding intelligence. The transverse character of IoT systems and various components associated with the arrangement of IoT systems have confronted impediments in the form of security and trust. There is a requirement to efficiently secure the IoT environment. The present study recommends a framework for impediments to secure and trustworthy IoT environments.

Design/methodology/approach

The present study identifies thirteen potential impediments to secure and trustworthy IoT environment. Further, a framework is developed employing Total Interpretive Structural Model (TISM) and Cross-Impact Matrix Multiplication Applied to Classification (MICMAC) approach. The integrated approach is employed as TISM organizes inter-relations among the identified impediments, while MICMAC analysis organizes interpretations related to the driving and dependence power of the impediments.

Findings

The results from the study represents that security of IoT from arbitrary attacks is the impediment that has attained the highest driving power. The impediments such as “security of IoT from arbitrary attacks”, “profiling” and “trust and prominence structure” are identified at the top level in the analysis.

Research limitations/implications

The previous studies highlight the facilitating contribution of IoT on various devices but neglect the impediments that can contribute towards a safe and trustworthy IoT environment. Also, the present study has its limitations as it depends upon the experts’ recommendations and suggestions.

Originality/value

The existing framework could be beneficial in constructing policies and suggestions to efficiently cater the impediments to a secure and trustworthy IoT environment.

Abstract

Purpose

This article aims at - exploring and prioritizing the barriers to adoption of digitization in supply chains (SCs), categorizing them into sustainability triple bottom line (STBL) based upon their direct impact and suggesting digital technologies to address each barrier.

Design/methodology/approach

A five-phase methodology is used which consists of an exploration of 44 barriers to the adoption of digitization in SCs, analysis of 44 barriers for mean, standard deviation and Cronbach alpha based on questionnaire-based feedback of 25 experts, extraction of 10 most significant barriers through 05 experts, followed by categorization of the barriers into STBL referring to their direct impact on STBL, prioritization of ten barriers using Fuzzy Technique for Order Performance by Similarity to Ideal Solution and recommendation of digital technologies to address each barrier.

Findings

While all the barriers considered in this study significantly impede the adoption of digitization in SCs, lack of top management commitment (B1) is found to be most crucial while lack of culture toward use of information and communication technology required for digitization (B3) has minimum impact. Large investment in digital infrastructure (B6), difficulty in integration of cyber physical systems (CPSs) on varied platforms (B8) and lack of experts having knowledge of digital technologies (B2) are equally important barriers requiring more attention while adopting digitization in SCs.

Research limitations/implications

This study is mainly based on feedback from 25 seasoned experts; a wider cross section of experts will give more insight.

Practical implications

The outcomes are very significant for organizations looking to adopt digitization in their SCs. Simultaneous consideration to all the barriers becomes impractical hence prioritization of same will be useful for the SC managers to benchmark their preparedness and decide strategies for the adoption of digitization with due consideration toward the impact of barriers on STBL. The digital technologies recommended will further aid in planning the digital strategies to address each barrier.

Originality/value

A unique approach to explore, analyze, prioritize and categorize the barriers to adoption of digitization in SCs is used to provide a deeper understanding of factors deterring the same. It implies that a supportive top management along with systematic allocation of finances plays a crucial role. The importance of availability of digital experts for integrating CPSs on a single platform is also highlighted. The digital technologies recommended will further assist the organizations toward adoption of digitization in SCs with due consideration to STBL.
