PepsiCo Deploys AI-Driven Pricing and Promotion Optimization at Scale

Effective pricing and promotion planning constitutes a central pillar of strategic revenue management for firms operating in highly competitive and dynamic markets. These planning activities require the simultaneous consideration of demand elasticity, competitor actions, channel and market specific constraints, and financial objectives. As the dimensionality and interdependencies inherent in these problems increase, manual or traditional approaches become suboptimal and insufficient. In this context, Operations Research provides a robust methodological foundation for scalable, data-driven decision support systems that can optimize complex planning processes across large product and customer portfolios. This paper presents two large-scale optimization systems developed and deployed at PepsiCo to support Revenue Growth Management initiatives: PromoAI and PricingAI. PromoAI couples machine learning-based promotional forecasts with a mixed-integer linear programming model to optimize promotional calendars across trade channels, searching millions of product-promotion-timing combinations for the one that maximizes PepsiCo and retailer revenues subject to customizable business constraints. PricingAI optimizes base prices across product portfolios over multi-period horizons, using Bayesian hierarchical models to estimate own- and cross-price elasticities and competitive interactions, then feeding these into a nonlinear programming engine that recommends price changes aligned with revenue and margin targets under operational constraints. Together, these systems demonstrate the feasibility and scalability of advanced optimization in large-scale enterprise environments. They highlight the value of integrating statistical learning with mathematical programming to enable enterprise-level, automated decision-making that is both data-informed and aligned with strategic business objectives.

Digital-analog quantum genetic algorithm using Rydberg-atom arrays

Digital-analog quantum computing (DAQC) combines digital gates with analog operations, offering an alternative paradigm for universal quantum computation. This approach leverages the higher fidelities of analog operations and the flexibility of local single-qubit gates. In this paper, we propose a quantum genetic algorithm within the DAQC framework using a Rydberg-atom emulator. The algorithm employs single-qubit operations in the digital domain and a global driving interaction based on the Rydberg Hamiltonian in the analog domain. We evaluate the algorithm performance by estimating the ground-state energy of Hamiltonians, with a focus on molecules such as $\rm H_2$, $\rm LiH$, and $\rm BeH_2$. Our results show energy estimations with less than 1% error and state overlaps nearing 1, with computation times ranging from a few minutes for $\rm H_2$ (2-qubit circuits) to one to two days for $\rm LiH$ and $\rm BeH_2$ (6-qubit circuits). The gate fidelities of global analog operations further underscore DAQC as a promising quantum computing strategy in the noisy intermediate-scale quantum era.

Trends in smart lighting for the Internet of Things

Smart lighting is an underlying concept that links three main aspects: solid-state lighting (SSL) technologies, advanced control and universal communication interfaces following global standards. However, this conceptualization is constantly evolving to comply with the guidelines of the next generation of devices that work in the Internet of Things (IoT) ecosystem. Modern smart lighting systems are based on light emitting diode (LED) technology and involve advanced drivers that have features such as dynamic spectral light reproduction and advanced sensing capabilities. The ultimate feature is of additional advanced services serving as the hub for optical communications that allows coexistence with traditional Wi-Fi gateways in indoor environments. In this context, lighting systems are evolving to support different wireless communications interfaces compatible with the IoT ecosystem. Market tendencies of SSL systems predict the accelerated expansion of connected IoT lighting control systems in different markets from smart homes and industrial environments. These systems offer advanced features never seen before such as advanced spectral control of the light source and also, the inclusion of several communication interfaces. These are mainly wired, radiofrequencies (RF) and optical wireless communications (OWC) interfaces for advanced services such as sensing and visible light communications (VLC). In this paper we present how to design and realize IoT-based smart lighting systems for different applications using different IoT-centric lighting architectures. Finally, different standards and aspects related to interoperability and web services are explained taking into account commercial smart lighting platforms.
