Abstract:

The successful implementation of push-pull supply chain management strategy has an important role in improving the competitiveness of an organization. The objective of a push-pull strategy is to minimize the holding of inventory level in finished form and rather produce finished goods from semi-finished inventory only upon receiving final order. One of the vital building blocks of push-pull supply chain strategy is postponement. The main objective of this review paper is to discuss the concept of postponement and its sub-categories such as product postponement and process postponement and their benefits. Then it is investigated how two prominent fast fashion retailers who are also categorized as original brand manufacturers in the apparel value chain apply the two variants of process postponement e.g. process standardization and process re-sequencing in their manufacturing operations to activate push pull supply chain strategy. The push-pull supply chain strategy in turn helps to reduce their order-to-delivery lead time to stores, reduce inventory holding level and minimize both physical costs and market mediation costs. The paper ends with concluding remarks. A framework is developed to illustrate the push-pull supply mechanism. This paper is a useful resource for practitioners in apparel supply chain willing to remove inefficiencies, costs and risks in their operations.

Abstract:

The article focuses on the procurement need specification of goods to support the operations of organisations, and how product supply chain processes are organised to fulfil customers’ procurement needs. Ten methods of procurement need specification for business purposes are dealt with. Product supply chain processes are executed as either ‘push’ or ‘pull’, or ‘push-pull’ oriented. Each of the approaches is discussed. Summaries of (a) the characteristics of the push and pull portions of supply chains; and (b) the spectrum of supply chain responses to customer demands are supplied

Abstract:

Purpose Previous researchers have studied push and pull contracts in the single product scenario, although in practice, supply chains often produce and sell multiple products. In a multiproduct scenario, the sales of a product will be influenced by its complements or substitutes, which requires consideration when the supply chain members negotiate contracts. This paper aims to fill this gap by studying push and pull contracts in a supply chain which distributes two products to a market and discusses how the degree of complementarity/substitutability between the two products affects the supplier’s decisions and supply chain efficiency. Design/methodology/approach The paper uses the model of a single-supplier, single-retailer supply chain which sells a product with a long lead time and another product with a short lead time simultaneously in a market. This research compares the production quantity and supply chain efficiency under a push contract with those under a pull contract. Findings First, when the two products are complements, the equilibrium production quantity of Product 2 is higher under a pull contract than that under a push contract. Second, a pull contract is found to be optimal for both the supplier’s profit and supply chain efficiency when the two products are complements, while if they are substitutes, then a push contract is the better choice in some situations. Originality/value The existing literature discusses push and pull contracts in the single product scenario. The current paper pays attention to the two-product scenario and investigates how the complementarity/substitutability degree between the two products affects the supplier’s decisions and supply chain efficiency.

Abstract:

The reuse of iron and steel scrap has high economic value as well as ecological benefits. By analyzing existing process of iron and steel scrap recycling, this paper studied the internal and external conflicts that blocked the smooth going of iron and steel scrap recycling process from the perspective of supply chain. To coordinate these conflicts, a push-pull iron and steel scrap supply chain was built to recover iron and steel scrap resources as more as possible in purpose of environmental protection by push strategy and match market demand by pull strategy. The results indicate that push-pull supply chain is an effective mode that well fit into economic demand as well as environmental demand in iron and steel scrap recycling process.

Abstract:

Purpose The research purpose of this paper is to confirm that internal overvoltages in the push–pull power inverter can be used to improve the discharge ignition in the gliding arc discharge (GAD) plasma reactor. Design/methodology/approach Investigations are based on the acquisition of voltage changes that occur together with the development of the discharge column and the imaging the GAD with the use of a high-speed camera. Findings The power supply has the distinctive feature of not having the switching overvoltages completely extinguished, as it is in typical push–pull inverters. The overvoltages still exist but only dangerous peaks are cut off. The remaining ones, of a dumped resonance character (Figure 3), are transferred to the secondary coil of the transformer. Correctly shaped overvoltages are used for ignition improvement in the GAD reactor. Practical implications GAD plasma reactors have many applications for pollution control, disinfection and sterilization of surfaces and for plasma deposition, surface functionalization, as well as in agricultural and medical treatment. Investigations prove the push–pull inverter’s advantages in comparison with the transformer-type power supply. Properly configured push–pull inverters have good ignition properties and control options, allowing to generate, desirable for many applications, homogeneous non-thermal plasma. Originality/value The idea of using switching overvoltages in transistors of push–pull switching-mode power supplies is new and has not been previously used to improve discharges ignition in a non-thermal plasma reactor.

Abstract:

To explore the attributes of cluster supply chain, and provide its driving model (2P&2BP) for more effective and more efficient way in implementing mass customization. The paper analyzes cluster supply chain driving model for implementing mass customization manufacturing using data from case study from 8 garment and IT industrial clusters. In process of implementing mass customization, we found that cluster supply chain has supplying level, marketing level and supplementing level to support its driving model (2P&2BP: Pull/push/burst power/bottleneck press) rather than conventional pull\push model. thus SMEs (small and medium-sized enterprises) in industrial cluster would have chances to extensively participate cooperate with core companies in the form of supply chain, thus expanding gradually.

Abstract:

Purpose The purpose of this paper is to examine the push effect of risk on supply chain (SC) performance, a new concept in the SC risk body of literature, at service-oriented firms. Design/methodology/approach Two models were compared: first, contains relationships between risks that show the mechanism of the push effect, i.e. the theoretical model. The other, only exists in direct effects of risks on SC performance, i.e. the competitive model. Findings Test results proved that the mechanism of the push effect can increase the degree of impact of each and all risks on outputs. By the push effect, risks can explain up to 65 percent variance of SC performance compared with 52 percent of the model without push effect. Moreover, the research found two kinds of the push effect: positive – increasing the impact of “pushed” factors on outputs and vice versa for negative. Research limitations/implications The mechanism of the push influence will be broken if mutual interaction among risks was minimized. Practitioners and managers can apply the resultant model as a “road map” in their context to achieve this purpose. Originality/value Vargo and Lusch (2008) argued that service-oriented firms will be a new trend since the modern-day industry tends to more focus on customer demand. SC management gradually shifted toward demand chain management that organizations will not make and sell units of output but producing customized services to customers (Walters, 2008). This transformation has led to the emergence of new risks, the impact of risk on the SC also varies and the mismatch of the current risk mitigation strategies (Lusch et al., 2007). Dealing with these changes is the purpose of this research.

Abstract:

In this paper, the relationship between the assumptions in the supply-driven and the demand-driven input-output model is discussed. A necessary and sufficient condition is given for the stability of the input coefficients, the output coefficients, and both coefficients. For both models, the effects of a demand pull on the total outputs and on the primary inputs are analytically expressed. Also, the effects of a supply push on the total outputs and on the final outputs are expressed, again for both models. In general, the assumption of fixed input coefficients in the demand-driven model does not hold, but computations are still based on it. A necessary and sufficient condition is given for the correctness of the computed total outputs, both for a demand pull and a supply push. Similar results are obtained for the supply-driven input — output model.

Abstract:

A fully integrated push–push voltage controlled oscillator (VCO) working in K-band with a large tuning range and a low phase noise fabricated in a 0.18 μm SiGe BiCMOS technology is presented. Multi-coupled LC tanks are used to improve the tuning range, power consumption and phase noise. Digital tuning varactors are used to maintain a low VCO tuning sensitivity (K VCO ) and maximum frequency overlap. The VCO achieves a frequency tuning range (FTR) of 17% at 12 GHz, a phase noise of -106.62 dBc/Hz at 1 MHz offset and consumes 7 mW from 1.8 V supply.

Abstract:

A welding system based on a push- pull wire feeder was designed and how it works was analyzed. The system included the welding power supply, the wire feeding system, and the coordination controller. The power supply used a current mode PWM IC UC3846 as the controller, which made sure the security and the dynamitic responsibility of the system. The critical fact to realize the push-pull wire feeding system was that a small inertia and fast response AC servo motor was selected. TMS320F2808 was used as the core coordination controller of the system, which made the welding power source and the wire feeding system work coordinately. The motor will pull the wire back when the arc was in the period of short-circuiting, and push the wire forward when the arc was in arc period. The results proved the system can meet the welding demands.

Abstract:

Supply chain under partial cross ownership (PCO) refers to the dyad in which each one holds part of its partners shares. In a two-echelon push supply chain under the partial cross ownership, when the operational decisions are bargained, the supply chain is coordinated, and the allocation of the chain profit is dependent on the bargain coefficients and the reserve profits, and independent of the PCO structure: letting the retailer hold part of the suppliers shares doesnt affect the chain efficiency and both players profits. Similarly, letting the supplier hold part of the retailers shares doesnt affect the chain efficiency and both players profits.

Abstract:

Purpose – The purpose of this paper is to investigate how business uncertainty affects the implementation of supply chain integration (SCI). More importantly, this research divides business uncertainty into four dimensions and SCI into three dimensions to examine the role of each dimension. In addition, it investigates the moderating effects of manufacturing approaches, such as push and pull, in the relationship between SCI and performance. Design/methodology/approach – Through a structured survey, this study collected 259 responses from supply executives, and supply and purchasing managers of US manufacturing firms. The empirical data analysis was done by using the partial least squares technique. Findings – The results empirically support the findings that business uncertainty positively affects implementation of SCI. Among the four dimensions of business uncertainty, dynamism and hostility significantly affect implementation of internal integration, integration with suppliers, and integration with customers. In addition, manufacturing approaches, such as push and pull, have a moderating effect on the relationship between SCI and performance. Practical implications – This study collected survey responses from a manufacturing firm in the supply chain to assist managers to find a solution while dealing with business uncertainty through the implementation of SCI. It also emphasizes manufacturing approaches, such as push and pull, in implementing SCI to improve performance. Thus, supply and purchasing managers should consider the business uncertainty that they are dealing with while developing their supply chain strategy. Originality/value – To the best of the authors’ knowledge, this study is the first to provide meaningful insights on the effects of SCI toward dealing with business uncertainty. More importantly, by dividing the dimensions of business uncertainty and SCI, this study presents empirical evidence of the significant role of supply chain practices in uncertain business conditions. In addition, this study addresses the gap in extant literature and shows that managers need to consider their manufacturing approach in SCI to improve business performance.

Abstract:

The existing push methods of supply chain information in logistics parks stay on the analysis of data surface, which leads to higher Mae value. Therefore, this paper proposes a push method of supply chain information in logistics parks based on the Internet of Things technology. Firstly, RFID structure is designed by introducing RFID, GPS, infrared, and other Internet of Things technologies to encode the materials in the logistics warehouse; secondly, the supply chain model of the logistics park is established to obtain the general ontology element model of the node enterprises in the supply chain of the park and the interaction business situation model between the node enterprises in the supply chain of the park. Finally, the average value of the node score is subtracted from the score of the node to calculate the information centralized scoring, as well as the establishment of Spark operation framework, to achieve the logistics park supply chain information pushing. In the simulation experiment, the international land port logistics park of a city is selected as a case to test. The experimental results show that the information pushing method of logistics information park supply chain based on Internet of Things technology has higher recommendation accuracy and better performance.

Abstract:

The amplification of demand order variability germinates from distorted demand information upstream while sometimes reacting to demand-driven inventory positioning influenced by the custodians of downstream information. This studyuses factor analysis to tentatively develop a supply chain model to enhance the competence of supply chain performance in terms of responsiveness, connectivity and agility. The results of the analysis indicate that the magnitude of control on the bullwhip effect and access to economic information on demand orders in the supply chain network are associated with the modelling of the push-pull theory of oscillation on three mirror dimensions of supply chain interrelationships (inventory positioning, information sharing and electronically-enabled supply chain systems). The findings provide the perspective on managing amplification in consumer demand order variability upstream in the supply chain network while enhancing the overall efficiency of supply chain performance. This article provides insight into the use of innovative strategies and modern technology to enhance supply chain visibility through integrated systems networks.

Abstract:

Abstract This article contributes to and connects the literature on spatial innovation diffusion, entrepreneurship, and industry life-cycles by disentangling the relevance of local demand and supply in the adoption of wind energy production. More precisely, we evaluate the strength of local supply–push effects with those of local demand–pull over the course of the evolution of an industry and its main product evolution. By using Bayesian survival models with time-dependent data of wind turbine deployment and firm foundation for 402 German regions between the years 1970 and 2015, we show that the spatial evolution of the German wind energy industry was more strongly influenced by local demand–pull than local supply–push processes. New producers are found to emerge in proximity to existing local demand for wind turbines. No evidence was found for producers being able to create local demand for their products by pushing the adoption of the technology in their regions.

Abstract:

In this work, a novel and efficient approach is proposed to optimize linearity and efficiency of a power amplifier used in mobile communication applications. A linear and high performance push amplifier is designed and analyzed to extract design equations for an optimum performance. The proposed push amplifier has two sections; an analog section and a switching section. The analog section provides the required linearity and the switching section guarantees the satisfaction of the total efficiency level. Double power supply scheme is used in push amplifiers to enhance its performance. Two separate power supplies are employed for linear and switching sections of push amplifiers which have different voltage levels. The implemented circuit is simulated using HSPICERF with TSMC models for active and passive elements. The proposed power amplifier (PA) provides a maximum output power of 25 dBm and power added efficiency (PAE) as high as 51% at 2.5 GHz operation frequency. At 1-dB compression point, this PA exhibits output power of 25 dBm with 48% PAE and 4.5% error vector magnitude (EVM) which is appropriate for 64QAM OFDM signals.

Abstract:

The remanufacturing industry plays a significant role to improve the utilization of resources and contribute to environmental protection and sustainable development. E-commerce channel (e-channel) has become an important retail channel. The multi-period closed-loop supply chain network of electronic channels (E-CLSCN) is studied. Moreover, this study considers the influence of consumers’ preference for products and artificial intelligence push (AI-push) on network balance under the conditions of dynamic and static. The network consists of manufacturers, remanufacturers, and demand markets. Remanufacturers are responsible for collecting and remanufacturing. The multi-period E-CLSCN model is established through variational inequalities. The study finds that whether dynamic or static, consumers’ preference for new products (NP) has positively correlated with the profits of manufacturers and the whole E-CLSCN. Consumers’ preference for remanufacturer products (RP) has only positively correlated with the profits of remanufactures. In the aspect of AI-push, the manufacturers’ AI-push has positively correlated with the profits of the entire players of E-CLSCN, while the remanufacturers’ AI-push has only positively correlated with the profits of the remanufacturers. Also, considering the multi-period, the sensitivity of the demand markets for the investment of manufacturers’ and remanufacturers’ AI-push gradually reduces, and the marginal benefit of AI-push gradually decreases. Finally, this paper addresses interesting managerial insights from the perspective of government and enterprises. Under the dual objectives of environmental protection and economic interests of enterprises, this study provides a reference for governments and enterprises to develop relevant dynamic policies. Namely, the government formulates dynamic environmental protection measures, and enterprises formulate dynamic strategic plans and implement government policies.

Abstract:

Aiming at the problems of the choice of system parameters has great influence on stability of system in the push-pull DC/DC converter system. The relationship between system parameters and system stability was studied based on the push-pull DC/DC converter simulation model of MATLAB. Due to the push-pull DC/DC converter system is nonlinear, the system was analyzed by poincare mapping graph. This paper mainly analyzed the influence of the ratio of converter transformer on system stability. It is shown by simulation that the system operation state transferred from stable period to chaos, when the value of transformer ratio changed from 7 to 4. The study results are valuable for the design of switching power supply system parameters, and would have a wide application foreground.

Abstract:

This paper studies the determinants of China's inflation and finds that demand-pull factors have been more important than cost-push factors in driving the inflation in the past decade. Because China's economic growth will gradually moderate and because the adjustment of the prices of the factors of production is also underway, the cost-push factors may soon play a more significant role in driving future inflation. Thus the Keynesian-style demand-side policy will not be enough to control inflation. More attention must now be given to supply-side management—such as dismantling monopolies, boosting private investment, encouraging innovation, and improving productivity—to mitigate the medium- to long-term inflation pressure.

Abstract:

This paper presents an implementation of the DC/DC push–pull converter for an uninterruptible power supply (UPS). Some classical DC/DC converters are presented and analyzed for pointing out their advantages and drawbacks. Besides, an original system based on a push-pull converter associated with a dynamic modulation control is chosen. The main advantage is the possibility to control the delivered electric power in a wide range from very low level to high level of voltage within the same basic architecture. It can reduce the switching power losses and increase the power conversion efficiency. This paper proposed a new control scheme of the DC/DC converter and DC/AC inverter. The suggested system consists of a high efficiency DC/DC converter and a singlephase DC/AC inverter has been simulated using Matlab/Simulink and designed basing on the DSP TMS320F28027. Both results show high performances of the DC link and AC load voltages, when load changes from zero to rated. The performance of the proposed system has been verified through a 1kW prototype of the system for a 50 Hz/220-230 VAC load sourcing by two series connected batteries of 12V. The proposed DC/DC converter achieves a high efficiency of 93.0%. The system including the DC/DC converter and DC/AC inverter achieves an efficiency of 91.2% and Total Harmonic Distortion (THD) of AC load voltage reached 1.9%.

Abstract:

The era of evolution in power electronic systems has led to a widespread displacement of power supplies operating at mains frequencies. Switched-mode power inverters offer possibilities incomparably higher than mains transformers. These trends have also entered into plasma technologies, including GlidArc plasma processing. The article presents the use of an inverter power supply for a miniaturized GlidArc. It is a demonstration of using a push–pull topology in an unusual application. A special part is devoted to parasitic phenomena in the inverter and the implementation of switching overvoltages as a way of improving the ignition parameters of the power supply. The results of the tests with a plasma reactor in air conditions as a process gas are also presented.

Abstract:

The paper presents the results of the study concerning supply chain models which was conducted by the author in Polish garment industry enterprises. The goal of the paper was to identify the types of supply chain models in this sector. The research methods were interviews and direct observations of manufacturing and logistics processes in clothing companies. Four types of supply chains models were characterized on the examples of supply chains of various companies. The criteria taken into consideration when characterizing the models included but were not limited to: the supply chain leader, the manufactured products (mass or individualized), the material flow strategy (push, pull), and the geographical location of the supply chain nodes. The factors differentiating these models were related to competitiveness – first of all, the price, the quality of products and services, the time of delivery, the accessibility of products, the extent of the product range.

Abstract:

Vendor Managed Inventory (VMI) System with Consignment Inventory (CI) policy is a solution for many supply chain leaders in a highly competitive market. In this paper, totally eight different inventory supply chain models are studied. The profit function of supplier and manufacturer in different environments are compared in order to show the profitability of the overall supply chain management system in a manufacturing industry with different time horizons. The inventory systems are applied on a supply chain consisting of a single supplier and a manufacturer. The main focus of this study is to analyze the effect of payment deferral and the time value of money in push and pull (Kanban) manufacturing systems when VMI-CI policy is applied.

Abstract:

AbstractWe present a continuously tunable 52-to-67 GHz push–push dual-core voltage-controlled oscillator (VCO) in a 40 nm bulk complementary metal–oxide–semiconductor (CMOS) technology. The circuit is suitable for 60 GHz frequency-modulated-continuous-wave radar applications requiring a continuously tunable ultra-wide modulation bandwidth. The LC-tank inductor is used to couple the two VCO cores. The fundamental frequency of the VCO can be tuned from 26 to 33.5 GHz, which corresponds to a frequency tuning range of 25%. The second harmonic is extracted in a non-invasive way using a transformer. The primary side acts simultaneously as a second harmonic filter. The VCO achieves in measurement a low phase noise of −91.8 dBc/Hz at 1 MHz offset at 62 GHz and an output power of −20 dBm. The VCO including buffers dissipates in the dual-core operation mode 60 mA from a single 1.1 V supply and consumes a chip area of 0.58 mm2.

Abstract:

Future concepts of operations purport that sophisticated information technology will significantly enhance mission effectiveness through two fundamental aspects: “speed of command” and “self synchronization.” On one hand, unlimited availability of information may serve to enhance the overall awareness of individuals and teams. On the other hand, unrestricted information push may serve to distract, overwhelm, and overload individuals and teams, thereby compromising their situation awareness and decision-making effectiveness. The question remains, how much information is enough? The purpose of this study was to assess the impact of information availability on decision-making by utilizing a four-person supply chain management simulation. View of information and communication were manipulated to constrain information availability. Results indicated better performance for conditions with more information availability, including unrestricted information push. Overall, these results illustrated the importance of capabilities such as anticipation and redundancy, which seem to be vital to collaborative tasks.
